In cardiovascular physiology, stroke volume (SV) is the volume of blood pumped from the left ventricle per beat. Stroke volume is calculated using measurements of ventricle volumes from an echocardiogram and subtracting the volume of the blood in the ventricle at the end of a beat (called end-systolic volume ) from the volume of blood just prior to the beat (called end-diastolic volume). The term stroke volume can apply to each of the two ventricles of the heart, although i… WebSummary. Stroke volume is the amount of blood the heart pumps with each beat. It is the difference between the end-diastolic volume and the end-systolic volume. The ejection fraction is the proportion of the end-diastolic volume that is pumped out with each beat. It is calculated as stroke volume divided by the end-diastolic volume.
