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.
Pacemakers also can monitor and record your heart's electrical activity and heart rhythm. Newer pacemakers can monitor your blood temperature, breathing rate, and other factors. They also can adjust your heart rate to changes in your activity. Pacemakers can be temporary or permanent. Temporary pacemakers are used to treat short-term heart problems, such as a slow heartbeat that's caused by a heart attack, heart surgery, or an overdose of medicine.
