German researchers have (1) a new generation of defibrillators and early-warning software aimed at offering heart patients greater protection (2) sudden death from cardiac arrest.
In Germany alone around 100,000 people die annually as a result of cardiac arrest and many of these cases (3) by disruption to the heart’s rhythm. Those most at risk are patients who have (4) suffered a heart attack, and for years the use of defibrillators has proved useful in diagnosing (5) disruptions to heart rhythms and correcting them automatically by intervening within seconds. These devices (6) a range of functions, such as that of pacemaker.
Heart specialists at Freiburg’s University Clinic have now achieved a breakthrough with an implanted defibrillator (7) of generating a six-channel electrocardiogram (ECG) within the body. This integrated system allows early diagnosis of (8) blood-flow problems and a pending heart attack. It will be implanted in patients for the first time this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautem have developed new computer software that renders the evaluation of ECG data (9) .
The overwhelming (10) of patients at risk will not have an implanted defibrillator and must for this reason undergo regular ECGs. "Many of the current programs only (11) into account a linear correlation of the data. We are, however, making use (12) a non-linear process that reveals the chaotic patterns of heart beats as an open and complex system, " Hagen Knaf says, " (13) changes in the heart beats over time can be monitored and individual variations in patients taken into account. " An old study of ECG data, based (14) 600 patients who had suffered a subsequent heart attack, enabled the researchers to compare risks and to show (15) the new software evaluates the data considerably better.

Everyone can dream. Indeed, everyone does dream. Those who (1) that they never dream at all actually dream (2) as frequently as the rest of us, (3) they may not remember anything about it. Even those of us who are perfectly (4) of dreaming night (5) night very seldom remember those dreams in (6) detail but merely retain an untidy mixture of seemingly unrelated impressions. Dreams are not simply visual-we dream with all our (7) , so that we appear to experience sound, touch, smell, and taste.
One of the world’s oldest (8) written documents is the Egyptian Book of Dreams. This volume is about five thousand years old, so you can (9) that dreams were believed to have a special significance even then. Many ancient civilisations believed that you (10) never wake a sleeping person as, during sleep, the soul had left the body and might not be able to return (11) time if the sleeper were suddenly (12) .
From ancient times to the present (13) , people have been (14) attempts to interpret dreams and to explain their significance. There are many books available on the subject of dream interpretation, although unfortunately there are almost as many meanings for a particular dream (15) there are books.

Life Expectancy in the Last Hundred Years
A. hundred years ago, life expectancy in developed countries was about 47; in the early 2lst century, men in the United States and the United Kingdom can expect to live to about 74, women to about 80, and these (1) are rising all the time. What has brought (2) these changes When we look at the life (3) of people 100 years ago, we need to look at the greatest (4) of the time. In the early 20th century, these were the acute and often (5) infectious diseases such as smallpox. Many children died very young from these diseases and others, and the weak and elderly were always at risk.
In the (6) world these diseases are far (7) today, and in some cases have almost disappeared. A number of (8) have led to this: improvements in sanitation and hygiene, the discovery and use of antibiotics, which (9) bacterial diseases much less dangerous, and vaccinations (10) common diseases. (11) people’s general health has improved with improvements in our general environment: cleaner air, better means of preserving food, better and warmer housing, and better understanding of nutrition.
Genetically, we should all be able to live to about 85 but (12) people do live longer today, there are still some big killers around that are preventing us from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease and strokes, and those (13) by viruses, such as influenza and AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect (14) people, but there are worrying trends in the developed world with problems such as obesity (15) more heart disease and illnesses such as diabetes at younger ages.
The killers today can be classed as "lifestyle diseases" , which means that it may be possible to halt their progress.

In the past twenty years, there has been an increasing tendency for workers to move from one country to another. (1) some newly independent countries have understandably restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, (2) increased oil incomes have enabled many countries to (3) outsiders to improve local facilities. (4) the Middle East has attracted oil-workers from the USA and Europe. It has brought in construction workers and technicians from many countries, (5) South Korea and Japan.
In view of the difficult living and working conditions in the Middle East, it is not (6) that the pay is high to attract suitable workers. Many engineers and technicians can earn at least (7) money in the Middle East as they can in their own country, and this is a major attraction. An allied benefit is the low taxation or complete lack of it. This increases the net amount of pay received by visiting workers and is very popular with them.
Sometimes a disadvantage has a compensating advantage. (8) , the difficult living conditions often lead to increased friendship when workers have to depend on each other (9) safety and comfort. (10) , many migrant workers can save large sums of money partly (11) the lack of entertainment facilities. The work is often complex and full of problems but this merely presents greater challenge to engineers who prefer to find solutions (12) problems rather than do routine work in their home country.
One major problem which (13) migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. (14) , migrant workers accept this disadvantage, along with others, because of the (15) financial benefits which they receive.

Young adults who are fit have a higher IQ and are more (1) to go on to university, reveals a major new study carried out at the Sahlgrenska Academy and Sahlgrenska University Hospital.
The results were recently published in the Proceedings of the National Academy of Sciences (PNAS). The study involved 1.2 million Swedish men doing military service who were born between 1950 and 1976. The research group analysed the (2) of both physical and IQ tests the youngsters took right after they started serving the army.
The study shows a clear link (3) good physical fitness and better results for the IQ test. The strongest links are for (4) thinking and verbal comprehension. But it is only fitness that plays a (5) in the results for the IQ test, and not strength. "Being fit means that you also have good heart and lung (6) and that your brain gets plenty of (7) , " says Michael Nilsson, professor at the Sahlgrenska Academy and chief physician at the Sahlgrenska University Hospital. "This may be one of the reasons (8) we can see a clear link with fitness, but not with muscular (9) . We are also seeing that there are growth factors that are important. "
By analysing data for twins, the researchers have been (10) to determine that it is primarily environmental factors and not genes that explain the link between fitness and a (11) IQ.
"We have also shown that those youngsters who (12) their physical fitness between the ages of 15 and 18 increase their cognitive performance," says Maria Aberg, researcher at the Sahlgrenska Academy and physician at Aby health centre. "This being the case, physical (13) is a subject that has an important place in schools, and is an absolute must if we want to do well in maths and other theoretical subjects. "
The researchers have also compared the results from fitness tests (14) national service with the socio-economic status of the men later in (15) . Those who were fit at 18 were more likely to go into higher education, and many secured more qualified jobs.

A number of (8) have led to this: improvements in sanitation and hygiene, the discovery and use of antibiotics, which (9) bacterial diseases much less dangerous, and vaccinations (10) common diseases. (11) people’s general health has improved with improvements in our general environment: cleaner air, better means of preserving food, better and warmer housing, and better understanding of nutrition.
Genetically, we should all be able to live to about 85 but (12) people do live longer today, there are still some big killers around that are preventing us from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease and strokes, and those (13) by viruses, such as influenza and AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect (14) people, but there are worrying trends in the developed world with problems such as obesity (15) more heart disease and illnesses such as diabetes at younger ages.
The killers today can be classed as "lifestyle diseases" , which means that it may be possible to halt their progress.

Young adults who are fit have a higher IQ and are more (1) to go on to university, reveals a major new study carried out at the Sahlgrenska Academy and Sahlgrenska University Hospital.
The results were recently published in the Proceedings of the National Academy of Sciences (PNAS). The study involved 1.2 million Swedish men doing military service who were born between 1950 and 1976. The research group analysed the (2) of both physical and IQ tests the youngsters took right after they started serving the army.
The study shows a clear link (3) good physical fitness and better results for the IQ test. The strongest links are for (4) thinking and verbal comprehension. But it is only fitness that plays a (5) in the results for the IQ test, and not strength. "Being fit means that you also have good heart and lung (6) and that your brain gets plenty of (7) , " says Michael Nilsson, professor at the Sahlgrenska Academy and chief physician at the Sahlgrenska University Hospital. "This may be one of the reasons (8) we can see a clear link with fitness, but not with muscular (9) . We are also seeing that there are growth factors that are important. "
By analysing data for twins, the researchers have been (10) to determine that it is primarily environmental factors and not genes that explain the link between fitness and a (11) IQ.
"We have also shown that those youngsters who (12) their physical fitness between the ages of 15 and 18 increase their cognitive performance," says Maria Aberg, researcher at the Sahlgrenska Academy and physician at Aby health centre. "This being the case, physical (13) is a subject that has an important place in schools, and is an absolute must if we want to do well in maths and other theoretical subjects. "
The researchers have also compared the results from fitness tests (14) national service with the socio-economic status of the men later in (15) . Those who were fit at 18 were more likely to go into higher education, and many secured more qualified jobs.

In the past twenty years, there has been an increasing tendency for workers to move from one country to another. (1) some newly independent countries have understandably restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, (2) increased oil incomes have enabled many countries to (3) outsiders to improve local facilities. (4) the Middle East has attracted oil-workers from the USA and Europe. It has brought in construction workers and technicians from many countries, (5) South Korea and Japan.
In view of the difficult living and working conditions in the Middle East, it is not (6) that the pay is high to attract suitable workers. Many engineers and technicians can earn at least (7) money in the Middle East as they can in their own country, and this is a major attraction. An allied benefit is the low taxation or complete lack of it. This increases the net amount of pay received by visiting workers and is very popular with them.
Sometimes a disadvantage has a compensating advantage. (8) , the difficult living conditions often lead to increased friendship when workers have to depend on each other (9) safety and comfort. (10) , many migrant workers can save large sums of money partly (11) the lack of entertainment facilities. The work is often complex and full of problems but this merely presents greater challenge to engineers who prefer to find solutions (12) problems rather than do routine work in their home country.
One major problem which (13) migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. (14) , migrant workers accept this disadvantage, along with others, because of the (15) financial benefits which they receive.

German researchers have (1) a new generation of defibrillators and early-warning software aimed at offering heart patients greater protection (2) sudden death from cardiac arrest.
In Germany alone around 100,000 people die annually as a result of cardiac arrest and many of these cases (3) by disruption to the heart’s rhythm. Those most at risk are patients who have (4) suffered a heart attack, and for years the use of defibrillators has proved useful in diagnosing (5) disruptions to heart rhythms and correcting them automatically by intervening within seconds. These devices (6) a range of functions, such as that of pacemaker.
Heart specialists at Freiburg’s University Clinic have now achieved a breakthrough with an implanted defibrillator (7) of generating a six-channel electrocardiogram (ECG) within the body. This integrated system allows early diagnosis of (8) blood-flow problems and a pending heart attack. It will be implanted in patients for the first time this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautem have developed new computer software that renders the evaluation of ECG data (9) .
The overwhelming (10) of patients at risk will not have an implanted defibrillator and must for this reason undergo regular ECGs. "Many of the current programs only (11) into account a linear correlation of the data. We are, however, making use (12) a non-linear process that reveals the chaotic patterns of heart beats as an open and complex system, " Hagen Knaf says, " (13) changes in the heart beats over time can be monitored and individual variations in patients taken into account. " An old study of ECG data, based (14) 600 patients who had suffered a subsequent heart attack, enabled the researchers to compare risks and to show (15) the new software evaluates the data considerably better.

Everyone can dream. Indeed, everyone does dream. Those who (1) that they never dream at all actually dream (2) as frequently as the rest of us, (3) they may not remember anything about it. Even those of us who are perfectly (4) of dreaming night (5) night very seldom remember those dreams in (6) detail but merely retain an untidy mixture of seemingly unrelated impressions. Dreams are not simply visual-we dream with all our (7) , so that we appear to experience sound, touch, smell, and taste.
One of the world’s oldest (8) written documents is the Egyptian Book of Dreams. This volume is about five thousand years old, so you can (9) that dreams were believed to have a special significance even then. Many ancient civilisations believed that you (10) never wake a sleeping person as, during sleep, the soul had left the body and might not be able to return (11) time if the sleeper were suddenly (12) .
From ancient times to the present (13) , people have been (14) attempts to interpret dreams and to explain their significance. There are many books available on the subject of dream interpretation, although unfortunately there are almost as many meanings for a particular dream (15) there are books.

Life Expectancy in the Last Hundred Years
A. hundred years ago, life expectancy in developed countries was about 47; in the early 2lst century, men in the United States and the United Kingdom can expect to live to about 74, women to about 80, and these (1) are rising all the time. What has brought (2) these changes When we look at the life (3) of people 100 years ago, we need to look at the greatest (4) of the time.

Heart specialists at Freiburg’s University Clinic have now achieved a breakthrough with an implanted defibrillator (7) of generating a six-channel electrocardiogram (ECG) within the body. This integrated system allows early diagnosis of (8) blood-flow problems and a pending heart attack. It will be implanted in patients for the first time this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautem have developed new computer software that renders the evaluation of ECG data (9) .
The overwhelming (10) of patients at risk will not have an implanted defibrillator and must for this reason undergo regular ECGs.

In the past twenty years, there has been an increasing tendency for workers to move from one country to another. (1) some newly independent countries have understandably restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, (2) increased oil incomes have enabled many countries to (3) outsiders to improve local facilities. (4) the Middle East has attracted oil-workers from the USA and Europe. It has brought in construction workers and technicians from many countries, (5) South Korea and Japan.
In view of the difficult living and working conditions in the Middle East, it is not (6) that the pay is high to attract suitable workers. Many engineers and technicians can earn at least (7) money in the Middle East as they can in their own country, and this is a major attraction. An allied benefit is the low taxation or complete lack of it. This increases the net amount of pay received by visiting workers and is very popular with them.
Sometimes a disadvantage has a compensating advantage. (8) , the difficult living conditions often lead to increased friendship when workers have to depend on each other (9) safety and comfort. (10) , many migrant workers can save large sums of money partly (11) the lack of entertainment facilities. The work is often complex and full of problems but this merely presents greater challenge to engineers who prefer to find solutions (12) problems rather than do routine work in their home country.
One major problem which (13) migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. (14) , migrant workers accept this disadvantage, along with others, because of the (15) financial benefits which they receive.

Young adults who are fit have a higher IQ and are more (1) to go on to university, reveals a major new study carried out at the Sahlgrenska Academy and Sahlgrenska University Hospital.
The results were recently published in the Proceedings of the National Academy of Sciences (PNAS). The study involved 1.2 million Swedish men doing military service who were born between 1950 and 1976. The research group analysed the (2) of both physical and IQ tests the youngsters took right after they started serving the army.
The study shows a clear link (3) good physical fitness and better results for the IQ test. The strongest links are for (4) thinking and verbal comprehension. But it is only fitness that plays a (5) in the results for the IQ test, and not strength. "Being fit means that you also have good heart and lung (6) and that your brain gets plenty of (7) , " says Michael Nilsson, professor at the Sahlgrenska Academy and chief physician at the Sahlgrenska University Hospital. "This may be one of the reasons (8) we can see a clear link with fitness, but not with muscular (9) . We are also seeing that there are growth factors that are important. "
By analysing data for twins, the researchers have been (10) to determine that it is primarily environmental factors and not genes that explain the link between fitness and a (11) IQ.
"We have also shown that those youngsters who (12) their physical fitness between the ages of 15 and 18 increase their cognitive performance," says Maria Aberg, researcher at the Sahlgrenska Academy and physician at Aby health centre. "This being the case, physical (13) is a subject that has an important place in schools, and is an absolute must if we want to do well in maths and other theoretical subjects. "
The researchers have also compared the results from fitness tests (14) national service with the socio-economic status of the men later in (15) . Those who were fit at 18 were more likely to go into higher education, and many secured more qualified jobs.

Life Expectancy in the Last Hundred Years
A. hundred years ago, life expectancy in developed countries was about 47; in the early 2lst century, men in the United States and the United Kingdom can expect to live to about 74, women to about 80, and these (1) are rising all the time. What has brought (2) these changes When we look at the life (3) of people 100 years ago, we need to look at the greatest (4) of the time. In the early 20th century, these were the acute and often (5) infectious diseases such as smallpox. Many children died very young from these diseases and others, and the weak and elderly were always at risk.
In the (6) world these diseases are far (7) today, and in some cases have almost disappeared. A number of (8) have led to this: improvements in sanitation and hygiene, the discovery and use of antibiotics, which (9) bacterial diseases much less dangerous, and vaccinations (10) common diseases. (11) people’s general health has improved with improvements in our general environment: cleaner air, better means of preserving food, better and warmer housing, and better understanding of nutrition.
Genetically, we should all be able to live to about 85 but (12) people do live longer today, there are still some big killers around that are preventing us from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease and strokes, and those (13) by viruses, such as influenza and AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect (14) people, but there are worrying trends in the developed world with problems such as obesity (15) more heart disease and illnesses such as diabetes at younger ages.
The killers today can be classed as "lifestyle diseases" , which means that it may be possible to halt their progress.

Everyone can dream. Indeed, everyone does dream. Those who (1) that they never dream at all actually dream (2) as frequently as the rest of us, (3) they may not remember anything about it. Even those of us who are perfectly (4) of dreaming night (5) night very seldom remember those dreams in (6) detail but merely retain an untidy mixture of seemingly unrelated impressions. Dreams are not simply visual-we dream with all our (7) , so that we appear to experience sound, touch, smell, and taste.
One of the world’s oldest (8) written documents is the Egyptian Book of Dreams. This volume is about five thousand years old, so you can (9) that dreams were believed to have a special significance even then. Many ancient civilisations believed that you (10) never wake a sleeping person as, during sleep, the soul had left the body and might not be able to return (11) time if the sleeper were suddenly (12) .
From ancient times to the present (13) , people have been (14) attempts to interpret dreams and to explain their significance. There are many books available on the subject of dream interpretation, although unfortunately there are almost as many meanings for a particular dream (15) there are books.

In the early 20th century, these were the acute and often (5) infectious diseases such as smallpox. Many children died very young from these diseases and others, and the weak and elderly were always at risk.
In the (6) world these diseases are far (7) today, and in some cases have almost disappeared. A number of (8) have led to this: improvements in sanitation and hygiene, the discovery and use of antibiotics, which (9) bacterial diseases much less dangerous, and vaccinations (10) common diseases. (11) people’s general health has improved with improvements in our general environment: cleaner air, better means of preserving food, better and warmer housing, and better understanding of nutrition.
Genetically, we should all be able to live to about 85 but (12) people do live longer today, there are still some big killers around that are preventing us from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease and strokes, and those (13) by viruses, such as influenza and AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect (14) people, but there are worrying trends in the developed world with problems such as obesity (15) more heart disease and illnesses such as diabetes at younger ages.
The killers today can be classed as "lifestyle diseases" , which means that it may be possible to halt their progress.

In the past twenty years, there has been an increasing tendency for workers to move from one country to another. (1) some newly independent countries have understandably restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, (2) increased oil incomes have enabled many countries to (3) outsiders to improve local facilities. (4) the Middle East has attracted oil-workers from the USA and Europe. It has brought in construction workers and technicians from many countries, (5) South Korea and Japan.
In view of the difficult living and working conditions in the Middle East, it is not (6) that the pay is high to attract suitable workers. Many engineers and technicians can earn at least (7) money in the Middle East as they can in their own country, and this is a major attraction. An allied benefit is the low taxation or complete lack of it. This increases the net amount of pay received by visiting workers and is very popular with them.
Sometimes a disadvantage has a compensating advantage. (8) , the difficult living conditions often lead to increased friendship when workers have to depend on each other (9) safety and comfort. (10) , many migrant workers can save large sums of money partly (11) the lack of entertainment facilities. The work is often complex and full of problems but this merely presents greater challenge to engineers who prefer to find solutions (12) problems rather than do routine work in their home country.
One major problem which (13) migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. (14) , migrant workers accept this disadvantage, along with others, because of the (15) financial benefits which they receive.

Young adults who are fit have a higher IQ and are more (1) to go on to university, reveals a major new study carried out at the Sahlgrenska Academy and Sahlgrenska University Hospital.
The results were recently published in the Proceedings of the National Academy of Sciences (PNAS). The study involved 1.2 million Swedish men doing military service who were born between 1950 and 1976. The research group analysed the (2) of both physical and IQ tests the youngsters took right after they started serving the army.
The study shows a clear link (3) good physical fitness and better results for the IQ test. The strongest links are for (4) thinking and verbal comprehension. But it is only fitness that plays a (5) in the results for the IQ test, and not strength. "Being fit means that you also have good heart and lung (6) and that your brain gets plenty of (7) , " says Michael Nilsson, professor at the Sahlgrenska Academy and chief physician at the Sahlgrenska University Hospital. "This may be one of the reasons (8) we can see a clear link with fitness, but not with muscular (9) . We are also seeing that there are growth factors that are important. "
By analysing data for twins, the researchers have been (10) to determine that it is primarily environmental factors and not genes that explain the link between fitness and a (11) IQ.
"We have also shown that those youngsters who (12) their physical fitness between the ages of 15 and 18 increase their cognitive performance," says Maria Aberg, researcher at the Sahlgrenska Academy and physician at Aby health centre. "This being the case, physical (13) is a subject that has an important place in schools, and is an absolute must if we want to do well in maths and other theoretical subjects. "
The researchers have also compared the results from fitness tests (14) national service with the socio-economic status of the men later in (15) . Those who were fit at 18 were more likely to go into higher education, and many secured more qualified jobs.

Everyone can dream. Indeed, everyone does dream. Those who (1) that they never dream at all actually dream (2) as frequently as the rest of us, (3) they may not remember anything about it. Even those of us who are perfectly (4) of dreaming night (5) night very seldom remember those dreams in (6) detail but merely retain an untidy mixture of seemingly unrelated impressions. Dreams are not simply visual-we dream with all our (7) , so that we appear to experience sound, touch, smell, and taste.
One of the world’s oldest (8) written documents is the Egyptian Book of Dreams. This volume is about five thousand years old, so you can (9) that dreams were believed to have a special significance even then. Many ancient civilisations believed that you (10) never wake a sleeping person as, during sleep, the soul had left the body and might not be able to return (11) time if the sleeper were suddenly (12) .
From ancient times to the present (13) , people have been (14) attempts to interpret dreams and to explain their significance. There are many books available on the subject of dream interpretation, although unfortunately there are almost as many meanings for a particular dream (15) there are books.

Life Expectancy in the Last Hundred Years

German researchers have (1) a new generation of defibrillators and early-warning software aimed at offering heart patients greater protection (2) sudden death from cardiac arrest.
In Germany alone around 100,000 people die annually as a result of cardiac arrest and many of these cases (3) by disruption to the heart’s rhythm. Those most at risk are patients who have (4) suffered a heart attack, and for years the use of defibrillators has proved useful in diagnosing (5) disruptions to heart rhythms and correcting them automatically by intervening within seconds. These devices (6) a range of functions, such as that of pacemaker.
Heart specialists at Freiburg’s University Clinic have now achieved a breakthrough with an implanted defibrillator (7) of generating a six-channel electrocardiogram (ECG) within the body. This integrated system allows early diagnosis of (8) blood-flow problems and a pending heart attack. It will be implanted in patients for the first time this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautem have developed new computer software that renders the evaluation of ECG data (9) .
The overwhelming (10) of patients at risk will not have an implanted defibrillator and must for this reason undergo regular ECGs. "Many of the current programs only (11) into account a linear correlation of the data. We are, however, making use (12) a non-linear process that reveals the chaotic patterns of heart beats as an open and complex system, " Hagen Knaf says, " (13) changes in the heart beats over time can be monitored and individual variations in patients taken into account. " An old study of ECG data, based (14) 600 patients who had suffered a subsequent heart attack, enabled the researchers to compare risks and to show (15) the new software evaluates the data considerably better.
