Listening to Your Heart. Your doctor will use a stethoscope to hear your heartbeat. The opening and closing of your heart's valves make a lub dub noise. The doctor can check your heart and valve health and hear your heart's rate and rhythm by listening to those sounds.
EKG recordings can help doctors diagnose a heart attack that's happening now or has happened in the past. This is especially true if doctors can compare a current EKG recording to an older one. An EKG also can show: Lack of blood flow to the heart muscle. A heart that's beating too fast, too slow, or with an irregular rhythm (arrhythmia) A heart that doesn't pump forcefully enough (heart failure) Heart muscle that's too thick or parts of the heart that are too big.
