"Webb4 okt. 2024 · Too much increase in heart rate shortens the diastolic time and decreases the end-diastolic volume, the force of contraction, and stroke volume. This results in decreased cardiac output. Stroke volume: When the stroke volume is increased, it would increase the cardiac output, provided that the heart rate is unchanged.

Webbend-diastolic pressure can be decreased, thereby reducing myocardial tension with a proportionate decrease in myo-cardial oxygen consumption. The coronary arterial perfu … WebbAortic pressure (AoP) is normally maintained by the baroreflex, which adjusts vascular resistance, venous tone, HR, and contractility [30 ]. However, this mechanism may be diminished in heart failure, partly due to reduced ventricular contractility. Adjusting pump speed to maintain AoP may compensate for a reduced baroreflex mechanism.
