1 Definition

Stroke volume refers to the volume of blood that is pumped out of a ventricle of the heart, usually the left ventricle, during a systole.

2 Physiology

Stroke volume (SV) is the difference between the end diastolic volume (EDV) and the end systolic volume (ESV):

  • SV = EDV - ESV

Since stroke volume is correlated with the force of ventricular systole, its exact value is load-dependent, e.g. having a higher value when running and a lower value when at rest. The average adult male has a stroke volume (at rest) between 70 and 100 ml.

Multiplying the stroke volume (SV, ml/heartbeat) by the heart rate (HR, beats/min) gives the cardiac output (CO, ml/min):

  • CO = SV x HR
