What is ejection fraction?
A healthy heart contracts (empties blood) and relaxes (refills blood) 60-80 times each minute. With each heartbeat, the heart pumps blood from the left and right ventricle.
In most cases, ejection fraction refers to the percentage of blood that's pumped out of the left ventricle with each heartbeat. For example, an ejection fraction of 50% means that 50% of the blood from the left ventricle is being pumped out during each beat.

What do ejection fraction numbers mean?
55 to 70% – Normal heart function.
40 to 55% – Below normal heart function. Can indicate previous heart damage from heart attack or cardiomyopathy.
Higher than 75% – Can indicate a heart condition like hypertrophic cardiomyopathy, a common cause of sudden cardiac arrest.
Less than 40% – May confirm the diagnosis of heart failure.
