Heart Problems: Living With a Pacemaker
What is an Actionset?
A pacemaker keeps your heart from beating too slowly. It's important to know how this device works and how to keep it working right. Learning a few important facts about pacemakers can help you get the best results from your device.
You may have a device that combines a pacemaker and an implantable cardioverter-defibrillator (ICD), which can shock your heart back to a normal rhythm. For more information on ICDs, see Heart Problems: Living With an ICD.

A pacemaker sends out mild electrical pulses that keep your heart from beating too slowly.
To be sure that your device is working right, you will need to have it checked regularly. Pacemakers can stop working because of loose or broken wires or other problems. Your doctor also will make sure that your pacemaker settings are right for what your body needs.
You may need to go to your doctor's office, or you may be able to get the device checked over the phone or the Internet.
Pacemakers run on batteries. In most cases, pacemaker batteries last 5 to 15 years. When it's time to replace the battery, you'll need another surgery, although it will be easier than the surgery you had to place the device. The surgery is easier, because your doctor doesn't have to replace the leads that go to your heart.
