Low Ejection Fraction (16)
... Ejection fraction (EF) is a measure of the amount of blood pumped out of the left ventricle (one of the two lower chambers of the heart). The term "ejection fraction" is used because it is a measurement of the blood pumped or "ejected" with each heartbeat. Because not all of the blood is ever comple ...
