WebStroke Volume. Stroke volume is the amount of blood ejected from the ventricle with each cardiac cycle. It can be readily calculated by subtracting the end-systolic volume from the end-diastolic volume. Multiplying the stroke volume by the heart rate yields the cardiac output, typically reported in liters per minute.

WebHow Afterload Affects Stroke Volume and Preload. As shown in the figure, an increase in afterload shifts the Frank-Starling curve down and to the right (from point A to B), which decreases stroke volume (SV) and increases left ventricular end-diastolic pressure (LVEDP).
