Web17 de fev. de 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 …
