  • Title: [Central hemodynamics as dependent on the method of bicycle exercise in sanatorium patients who have had a myocardial infarct].
    Author: Efremushkin GG, Belousova NS.
    Journal: Ter Arkh; 1998; 70(8):37-41. PubMed ID: 9770742.
    Abstract:
    AIM: To study central hemodynamics response to bicycle exercise with optimal pedalling rate (OPR) and in free-choice regimen of pedalling as regards the initial pedalling rate in postmyocardial infarction (PMI) patients on sanatorium treatment. MATERIALS AND METHODS: Bicycle ergometry and tetrapolar rheography examinations were performed in 124 PMI male patients. Bicycle exercise was carried out in three regimens: a) optimal pedalling rate (1), b) muscular load chosen by the patient at the first training kept further for daily training (2), c) free-choice daily load (3). RESULTS: In OPR 30 and 45 rpm, patients on regimen 3 improved their myocardial contractility both at rest and exercise. In OPR 60 rpm, exercise in regimen 1 was more effective. Regimen 2 was not effective. CONCLUSION: Hemodynamic effects were most pronounced (improved myocardial contractility in more effective cardiac performance) in the regimen of OPR 60 rpm.
