Stroke volume is determined by 3 factors
Did you know?
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 afterload. Corresponding to the oxygen uptake, women's need for blood … See more 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 See more • Berne RM, Levy MN (2001). Cardiovascular Physiology. Philadelphia, PA: Mosby.

SV is the volume of blood pumped by the heart (left ventricle) during each heart beat. Stroke volume variation is defined as: End-diastolic volume – End systolic volume during the left ventricular angiogram. SV normal range is between 60 and 120mL and both ventricles have similar volumes.
