chosen.content: The ejection fraction measurement shows what fraction of the blood that is inside the heart chambers is actually being pumped out into the body. A healthy ejection fraction is fifty percent or more. Below forty percent may indicate heart failure. Symptoms of heart failure include shortness of breath, irregular heartbeat, and swelling of the legs and feet.
