Cardiovascular disorders and sports,thletes is caused either by undiagnosed cardiac disease or it is due to a constitutionally large heart. In sports activities where physical exercise capacity can be correlated with cardiac size — such as in cycling, long-distance running, rowing — athletes who are born with a strong and large heart are more likely to achieve maximum Performance.

Importance of cardiovascular diseases for morbidity and mortality,ular diseases have become the major killers in developed countries (in 1985 51%, and in 1988 49.7% of deaths in West Germany were due to cardiovascular disease, and in the United States the percentage was 43% in 1988). Cardiovascular diseases are consistently being recognized as the number one cause

Now, such a recording, the electrocardiogram (Fig. 11), is the most frequently used Standard cardiovascular diagnostic test. The recorded changes in field potentials from th

Only repeated measurements may help in deciding whether there is sustained hypertension or whether there is intermittent (“labile”) hypertensive episodes, or stress-related hypertension (“white-coat hypertension”).

Cardiac arrhythmias,may be documented in healthy subjects. On the other hand, they may be a manifestation of severe cardiac disease and, finally, they are the most frequent cause of sudden cardiac death. It is possible to classify them according to where they originate and also within the following four categories.

The heart volume may increase from approximately 600 ml to more than 1200 ml, but this is not only caused by an increase in muscle mass (hypertrophy), but also by an increase in cardiac blood volume (dilat
