Rhythm and conduction abnormalitieschanges are bradycardia (reflecting an increased stroke volume and high vagal tone), atrioventricular (AV) conduction disorders (reflecting high vagal tone) and ventricular hypertrophy. The frequency of ECG abnormalities may vary according to the type of athletic pursuit..In one study, the minimum n

Effects of intensive physical conditioning on cardiovascular parameters of high-level athletess-country skiers. Electrovectorcardiogram, M-mode echocardiogram, maximal exercise testing and a 24-h Holter ECG were performed before and at the end of a 3-month span of intensive training. Among the cardiac parameters studied, the only statistically significant changes were, in skiers: prolongatio

Echocardiographic evaluation of the heart of athletes: cross-sectional and longitudinal observationsss. An isometric component in the sports activity will increase the ratio of wall thickness to internal radius, provided the activity is of sufficiently long duration. Left ventricular structure varies with the training state. Finally, although some significant differences in left ventricular functi

Aerobic exercise and cardiac size: an echocardiographic study of Rotterdam marathon runners in dimension as assessed by echocardiography, which is the most accurate method for such an analysis, is rather moderate [1–13, 15, 16]. Moreover, most of these studies include only a small number of athletes compared with non-athletic or even inactive controls. This may introduce some bias as such

The windsurfer’s heart years. Fifteen untrained male subjects, matched for age, height and weight were used as controls..Athletes showed a significant increase in LV end-diastolic dimension, posterior wall and septal thickness, with a greater estimated LV mass and cross-sectional area. In addition, the ratio of wall thic

An investigation of athlete’s heart by chest X-ray, electrocardiography and echocardiographyicant correlations were found between the radiologic heart volume and echocardiographic dimensions. However, the electrocardiographic parameters correlated poorly with heart volume and with the echocardiographic data. Therefore the degree of physiological cardiac hypertrophy in athletes cannot be ev

Abnormal electrocardiographic exercise test in middle-aged athletes: correlation with exercise myocaproblems of clinical clarification arise and further tests are required owing to the poor predictive value of exercise testing in asymptomatic subjects..An exercise thallium-201 myocardial scintigraphy was thus performed in 16 sportsmen, aged 27–54 years, who exhibited a positive exercise test durin
