Meaning of stroke volume
WebStroke volume is the amount of blood in one clean pump – in other words, what your heart pumps with each beat. It’s a measurement of how much blood goes through your body … 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.
