Stroke Volume: Definition, Formula, and Clinical Significance
Stroke volume (SV) is the volume of blood pumped by the left ventricle per heartbeat.
Formula: SV = End-diastolic volume – End-systolic volume
Key determinants:
- Contractility: Force of myocardial contraction
- Preload: Ventricular filling pressure (venous return)
- Afterload: Resistance the heart must overcome to eject blood
SV is a critical measure of cardiac pumping efficiency.
