[Potentials of paired bicycle ergometry tests in assessing the functional state of the cardiovascular system in ischemic heart disease patients with attacks of stenocardia of effort].

Cardiovascular response to physical stress simulated by paired bicycle ergometry was evaluated in 33 patients with coronary disease of functional class 3 or 4, within 1-1.5 months after myocardial infarction. In third-class patients, stress tolerance and hemodynamic support improved after the second bicycle ergometry performed 30 minutes after the first test. In the fourth-class patients, repeated exercise revealed a reverse pattern in the parameters examined.
