WebFeb 17, 2024 · The term "ejection fraction" is the amount of blood — as a percentage — that's pumped out of a filled ventricle with each heartbeat. The ejection fraction is usually measured only in the left ventricle. The left ventricle is the heart's main pumping chamber. It pumps oxygen-rich blood up into the body's main artery, called the aorta.

WebThe increase in cardiac output during moderate exercise is the result of increased stroke volume and increased heart rate. However, when roughly half of the maximal cardiac output is achieved, the stroke volume cannot increase further, which means that further increase in cardiac output depends on an increase in heart rate.
