(HealthDay News) -- A pacemaker is a small implanted device designed to help the heart beat properly and in a normal rhythm.
The U.S. National Heart, Lung, and Blood Institute says the following conditions may signal the need for a pacemaker:
- Your heart does not beat normally due to age or heart disease.
- You have had a procedure called atrial fibrillation to treat an arrhythmia -- the medical term for an irregular heartbeat.
- You take medication that slows your heartbeat, such as a beta blocker.
- You show symptoms of a slow heartbeat, including fainting.
- You have muscle problems that may trigger slow travel of electrical signals through the heart.
