Ejection fraction is commonly measured by an echocardiogram and serves as a general measure of a person's cardiac function. Ejection fraction is typically low in patients with the systolic form of congestive heart failure.
A Cardiac Rehabilitation, answered on behalf of Honor Society of Nursing (STTI) Normal ejection fraction of the heart is in the range of 60% to 80%. It can also be classified as normal, mildly reduced, moderately reduced and severely reduced without giving a percentage. The ejection fraction is used as a measure of the severity of heart failure and helps guide treatment. Please note: Symptoms do not always match the severity of the ejection fraction. Some very symptomatic patients can have normal ejection fractions and some patients with very low ejection fractions can have almost no symptoms of heart failure.
