title: [Effect of preliminary adaptation to moderate and intensive physical loads on cardiac electrical stability and contractile function in experimental myocardial infarct].
abstract: Preliminary adaptation of animals to a moderate swimming exercise prevented the fall of ventricular fibrillation electrical threshold and limited drastically the heart ectopic activity in acute myocardial infarction. Adaptation to intense stress, i.e. prolonged swimming with a load, had less preventive effect. The rationing of preventive exercise, to be used for the prophylaxis of myocardial infarction, is discussed.
