Video Summary
Stroke volume is the amount of blood the heart pumps with each beat. It is the difference between the end-diastolic volume and the end-systolic volume. The ejection fraction is the proportion of the end-diastolic volume that is pumped out with each beat. It is calculated as stroke volume divided by the end-diastolic volume. Cardiac output is the amount of blood the heart pumps in one minute and is equal to the heart rate multiplied by the stroke volume.
