What is considered to be a normal ejection fraction ?

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.

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).

In the neighborhood of 60% or more.

55%-65% is considered optimal, but many people have less than that.
