Heart rate - Wikipedia

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 ) … Ver más 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 mL … Ver más Men, on average, have higher stroke volumes than women due to the larger size of their hearts.

WebIn this figure, the control loop has an end-diastolic volume of 120 mL and an end-systolic volume of 50 mL. The width of the loop (end-diastolic minus end-systolic volume) is the stroke volume (70 mL). When inotropy is increased (at constant arterial pressure and heart rate) SV increases, which reduces the end-systolic volume to 20 mL.
