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. WebApr 10, 2024 · Cardiac output can be decreased by an increase in SVR through impedance of ejection of blood or the force that resists ventricular muscle contraction .
