[Diastolic heart function during bicycle ergometry in patients with hypertension and different mass of the left ventricle].

Changes in parameters for cardiac filling and pump functions during graded exercise were studied in 29 hypertensive patients with various left ventricular myocardial mass and 30 healthy subjects by unidirectional echocardiography. The volume of early diastolic filling decreased and that of diastasis and atrial systole increased with increasing left ventricular mass. These changes were found during graded exercises rather than at rest.
