Ejection fraction?

What is considered to be a normal ejection fraction ?

Answers:
A normal ejection fraction is 50-75%. This number represents the amount of blood that is pumped out of the left ventricle with each heart beat. Many things can lower this number; heart attack, valve dysfunction, and long-term untreated high blood pressure to name a few.

When the ejection fraction gets below 30%, people have symptoms of congestive heart failure; shortness of breath, weakness, and fluid retention. Now there are some new pacemakers for people with CHF that can improve your heart's efficiency. (see Medtronic Website for bi-ventricular pacemakers)

If you have heart disease, it is important to know your EF and do everything you can to preserve it. You and your doctor can develop a regimen of diet, exercise and medication that will preserve your current ejection fraction.

In the neighborhood of 60% or more.
55%-65% is considered optimal, but many people have less than that.
60 to 75%. The ejection fraction is the amount of blood ejected from the atria into the ventricles. At rest the ejection fraction is usually less than during stress(exercise).
