what test looks at ejection fraction
This test, often called an echo, shows your heart's movement. During this exam, your doctor places a wand on the surface of your chest. It sends ultrasound waves that show pictures of your heart's valves and chambers. Those images let your doctor look at how well your ticker is pumping. Your doctor may combine an echocardiogram with tests called Doppler ultrasound and color Doppler to check blood flow across your heart's valves. Ejection fraction (EF). It's a measure of how much blood is pumped out of your heart each time it beats.
