[Effect of an inpatient exercise therapy program on the R and RS amplitude in the stress ECG]. / Wirkung eines stationär durchgeführten Trainingsprogrammes auf die R- und RS-Amplitude des Belastungs-Ekg.

The ECG after work of 60 patients after an acute myocardial infarction was examined before and after a 4-week physical training as well as 6 months after the acute phase of the infarction. In the precordial leads the changes of the amplitude of the R-waves and the RS-complex as well as the depression of the ST-segment during the bicycle ergometer load and the delta-values were determined. The investigations evoked to the end of the training programme a significant decrease of the delta-values, which again increased at a later control. The change is explained by the haemodynamic and anti-ischaemic effect of the training programme.

[Indirect study of oxygen consumption of the heart muscle]. / Indirekte Untersuchung des Sauerstoffverbrauches des Herzmuskels.

The connection between the inner heart action in form of the double product and the physical functional capacity in watt (PWC) was controlled in patients with chronic ischaemic heart disease. For this purpose 64 patients with an average age of 47 years in the pulmological institute Mosdos and 25 patients with an average age of 53 years in the clinic for internal medicine of Berlin Humboldt University underwent a bicycle ergometer load. The double product, calculated from the systolic blood pressure and the heart rate, was regarded as measure for the myocardial oxygen consumption. It was established that there is a correlation between the inner heart action measured at the lover load level and the physical functional capacity in watt achieved simultaneously or later.
