what is a normal heart ejection fraction
Ejection fraction is calculated by the amount of blood pumped out of the heart with each beat divided by the amount of blood in the heart at its fullest. In other words, ejection fraction measures what percent of the blood in the heart is pumped out when the heart beats. A normal range for ejection fraction is 65 percent, plus or minus 12. That means that normal, healthy hearts only pump about 65 percent of the blood out of their heart with each beat. There are multiple ways to measure ejection fraction, including: Echocardiogram (ultrasound of the heart)
