WebTherefore, people estimate the volume based on the formula used to calculate heart rate and measurable factors that stroke volume estimates, like blood pressure. While stroke volume and heart rate can influence cardiac output, stroke volume does not change too much, with only small fluctuations even during exercises.

WebCardiac output (known as ‘Q’) is a measure of the amount of blood that is pumped out of the heart in one minute. ‘Q’ specifically refers to the amount of blood pumped out of the left ventricle as this is the ventricle that supplies blood to the muscles and organs of the body.

Stroke volume is the amount of blood ejected from the ventricle with each cardiac cycle. It can be readily calculated by subtracting the end-systolic volume from the end-diastolic volume. Multiplying the stroke volume by the heart rate yields the cardiac output, typically reported in liters per minute.

WebHeart rate increases proportionately with workload until heart rates close to maximal are attained. It is remarkable that exercise heart rates six to seven times resting values are not associated with a fall in stroke volume, which is maintained by splenic contraction, increased venous return, and increased myocardial contractibility.
