[The ECG on exercise (author's transl)].

The electrocardiogram on exercise with a graduated load on the bicycle ergometer has proved of value as a screening method for coronary heart disease and arrhythmias. A horizontal or descending ST junction depression of 0.1 mv in the left precordial lead is considered a significant ischemic reaction. The present paper reports the practical performance and evaluation of findings of the method. The prognostic significance of a pathological ECG on exercise with regard to the occurrence of a coronary heart disease and the progression of the disease are pointed out.
