title: [Diagnostic significance of changes in the diastolic period of the heart cycle in ischemic heart disease patients undergoing head-down tilt loading].
abstract: In 62 patients with angina pectoris of different functional classes, physical stress tolerance has been compared to changes of apexcardiographic variables in the postural test. It has been demonstrated that anginal patients have abnormal relaxation velocity and left ventricular filling. Passive volume redistribution test allows one to reveal diastolic myocardial dysfunction, severity of which is related to the degree of coronary insufficiency.
