[Comparative evaluation of cardiovascular function in patients after myocardial infarction during exercise test with the optimal and sub-optimal frequency of pedalling]

Abstract

Cardiovascular function was studied in 59 patients with myocardial infarction during their bicycle ergometer exercise performance at optimal and +sub-optimal pedalling rates. The total performance at the optimal rate was found to average 1.48 times more than that at the +sub-optimal rate. The efficiency of cardiovascular performance was achieved by a less increase in heart rate and systolic pressure. ECG changes resulting in exercise test cessation were observed in 7 and 30 cases at the optimal and +sub-optimal rates, respectively. It is concluded that physical training that fails to impose patients' rhythm and exercise capacity are more physiological and maximally safe.
