[ECG and 24-hour ECG findings in athletes of static and dynamic disciplines].
Endurance sports are associated with structural and functional changes in the myocardium. Physiologic changes representing cardiac adaptation to training are termed "athletic heart". ⋯ Resting ECG, echocardiography, and 24 hour ECG provide valuable cardiologic information in athletes. The heart rate was slower in all athletes and the PQ interval was longer as compared with controls. No serious arrhythmias or conduction abnormalities were noted. The duration of training and the presence of myocardial hypertrophy had no effect on electrocardiographic parameters.
