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 … See more Its value is obtained by subtracting end-systolic volume (ESV) from end-diastolic volume (EDV) for a given ventricle. $${\displaystyle SV=EDV-ESV}$$ In a healthy 70-kg man, ESV is approximately 50 … See more Men, on average, have higher stroke volumes than women due to the larger size of their hearts. However, stroke volume depends on several factors such as heart size, contractility, duration of contraction, preload (end-diastolic volume), and See more • The Gross Physiology of the Cardiovascular System • The Determinants of Cardiac Output (online video) See more • Berne RM, Levy MN (2001).
