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.
Diastolic heart failure may not lower the heart's ejection fraction. Ejection fraction is a measurement of how well the heart is pumping out blood. This ejection fraction is typically lower in people who have systolic heart failure.But in diastolic heart failure, your left ventricle may pump well during systole; it is just not filling with enough blood during diastole.iastolic heart failure may not lower the heart's ejection fraction. Ejection fraction is a measurement of how well the heart is pumping out blood. This ejection fraction is typically lower in people who have systolic heart failure.
