The body generates electrical impulses that cause the heart to beat. In some people, those electrical impulses don't happen in a normal pattern, which can cause the heart to beat too slowly, too fast or irregularly. A very slow heartbeat can lead to fatigue, lightheadedness, dizziness and fainting. In patients who are at risk for a very slow heart rate, doctors often recommend a pacemaker.
Most patients with a pacemaker can live a normal, active life. Patients do need to take some precautions such as carrying their medical ID card, which contains information about their device, and telling all of their heath care providers that they have a pacemaker.
The procedure for implanting a pacemaker is often routine and relatively easy for the patient. The health care team will tell the patient how to prepare for surgery and what to expect during the procedure.
