[Changes in stroke volume in ventricular asystole].

Change in the stroke volume in ventricular extrasystoles was studied in 27 patients. In patients with cardiac insufficiency a decrease in the extrasystolic stroke volume was more noticeable than in patients without cardiac insufficiency. "Hemodynamic debts" for extrasystolic and postextrasystolic contractions in patients with the presence and absence of cardiac insufficiency were undistinguished. In interpolated extrasystoles "hemodynamic debts" were less than in non-interpolated.
