[Comparative studies on influences of physical and psychological strain on the ECG in coronary disease patients].
In 7 patients suffering from heart infarction the electrocardiogram was telemetrically registered during telecast of the world championship in football 1974. The same patients were tested on a bicycle ergometer with standardized loads of 50, 75, 100 and 125 Watt for 3 minutes. Heart rate under psychial strain did not exceed the rate of 50 Watt on bicycle ergometer. Only 1 patient showed some extrasystoles during ergometry. Looking at television all patients developed extrasystoles, in one case 122. If the FRG took part in the game, ventricular extrasystoles were two times, auricular extrasystoles were four times more frequent than during games between foreign countries. It is concluded that psychical strain is able to produce dangerous arrhythmias in patients suffering from coronary heart disease. This danger cannot be proved by bicycle ergometry.
