title: [Veloergometric indicators in patients with acute myocardial infarct during the period of their activation].
abstract: Veloergometry was practised in 35 patients with acute myocardial infarction at the time of their activiation (mainly on the 45-50th day of the disease or 7-8 days after they have been put on the feet). The investigation was aimed at detecting some signs of coronary insufficiency and cardiac incompetence, as well as of the limit of physical activity of such patients at the time of stimulated physical performance. The patients under examination demonstrated a significantly reduced amount of the work performed, which averaged 327 kgm. Among the patients complaints that led to discontinuance of the exercises were general fatigue and that of the feet in particular, dyspnoea and sensation of air deficiency, anginal attacks and deranged cardiac rhythm. In 28 cases changes in the terminal part of the ventricular ECG complex were recorded. The T-V1 greater than T-V6 syndrome was also analyzed before and after veloergometry. Of interest are the ECG changes in 2 groups of the patients, viz. the 1st without any ECG indications of transmural infarction and the 2nd one presenting such signs. Changes in the terminal part of the ventricular complex recorded in patients of the 2nd group, combined with dyspnoea, asphyxia and marked tachycardia during veloergometry suggest the presence in them not only of the coronary, but also of the left ventricular insufficiency.
