A bicycle-ergometric study under continuous electrocardiographic and hemodynamic monitoring demonstrated that physical stress tolerance is conditioned by pre-existing myocardial contractility disturbance rather than the depth of heart muscle involvement (as evidenced by ECG) at early dates of myocardial infarction. The patients' capacity for doing exercise, on a stepwise basis, was limited by transitory myocardial ischemia as well as inadequate and incompetent hemodynamic support.
