What is a normal ejection fraction? A: Ejection fraction normally refers to measurements related to the left ventricle of the heart, and patients with an ejection fraction between 55 and 70 perc... Full Answer >
Typically, the left ventricle ejects 55% or more of its blood volume with each beat, so a normal ejection fraction is 55% (0.55) or higher. 1  An ejection fraction of 40 - 50% is considered âbelow normal.â Patients with heart failure most often have ejection fractions that are less than 40%. It is important to note that when doctors say the words âejection fractionâ they are referring to the ejection fraction of the left ventricle.
