Question asked by Jason from Hershey, Pennsylvania
What is a normal ejection fraction?
Answered by Dr. Brian Jaski
The ratio of the volume of blood ejected when the heart pumps is measured in a value of percentage. The normal limits of the measurement can depend on the type of test used to measure the change in left ventricular volume with each beat. On average, a heart at rest has an ejection fraction between 55-75%, never fully ejecting all the blood from the heart.
