[Evaluation of the results of ergometric studies]

An evaluation of some standardized and relative indices of ergometry is presented: heart rate and oxygen consumption as percentage of individual values, indices of chrono-, isotropic, aerobic and coronary reserves. The investigation is based on the study of 113 normal individuals, 363 hypertonic patients, and 100 patients with ischaemic heart disease. In all cases the maximum tolerable workload was tested by way of its step-wise increase, conducted under pulse, arterial pressure, ECG and oxygen consumption control. Some patients were examined after Obsidan and Dopegit therapy. The use of the relative values of the heart rate and oxygen consumption was shown to neglect the role of individual factors (sex, age, body weight). The determination of the relative augmentation of these indices, as well as of the arterial pressure permits to precise the state of functional reserves of the cardiopulmonary system, and can be used for the diagnosis and evaluation of therapeutic results.
