In 38 patients after myocardial infarction changes of the main parameters of the central haemodynamics have been found with the aid of tetrapolar transthoracic rheography and phonotachooscillography as compared with a control group (20 practically healthy individuals). A direct interrelationship has been found between the value of the stroke volume of the heart and individual tolerance to exercise as determined by bicycle ergometer. A regression equation was derived with which rough individual tolerance to exercise can be calculated by the value of the stroke volume. By the mathematical method of paired and multiple correlations the direct relationship of the value of the cardiac stroke volume with the degree of coronary and cardiac insufficiency has been found. The sequence of functional methods of examination and control at the sanatorium stage of rehabilitation of patients after myocardial infarction is discussed.
