Pacemaker

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.

Disorders in the heart's electrical system can lead to arrhythmias, or an abnormal heart rhythm. Some patients who have been diagnosed with a slow heart rate, known as bradycardia, may require a pacemaker. A pacemaker is a device that is implanted in the chest and can correct a slow heartbeat.

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.

Following the pacemaker implant procedure, the patient will stay in the hospital for one or two nights to make sure the wound is healing without complications and the device is working properly. Before discharging the patient, the health care team will provide instructions on how to care for the wound at home.
