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. To learn more about ICDs, see Heart Problems: Living With an ICD.
Pacemakers are small electrical devices that help control the timing of your heartbeat.
A pacemaker is implanted under the skin of your chest wall. The pacemaker's wires are passed through a vein into the chambers of your heart. The pacemaker sends out small electrical pulses that keep your heart from beating too slowly.
A pacemaker sends out mild electrical pulses that keep your heart from beating too slowly.
To be sure that your device is working right, your doctor will monitor your device 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.
Your doctor will check your pacemaker during regular office visits and remotely. Remote monitoring is done by telephone or through 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.
It's important to have your pacemaker checked regularly to make sure it is working right.
When you have a pacemaker, it's important to avoid strong magnetic and electrical fields. The lists below show some electrical and magnetic sources and how they may affect your pacemaker. For best results, follow these guidelines. These safety tips also apply to devices that combine an ICD and a pacemaker. If you have questions, check with your doctor.
Your doctor or the manufacturer of your pacemaker can give you a full list of things that you need to avoid and things that are safe to use.
Stay away from:
Use with caution:
Safe to use:
Most medical tests and procedures won't affect your pacemaker, except for MRI, which uses strong magnets. To be safe:
You can travel safely with a cardiac device. But you'll want to be prepared before you go.
You can drive if you have a pacemaker and you don't have any symptoms such as fainting. But right after you get a pacemaker, your doctor will likely ask you to not drive for at least a week after the device is implanted. This gives you time to heal.
Pacemakers often are used to improve your ability to exercise. Most people with pacemakers have active lives and can exercise. Talk to your doctor about the type and amount of exercise and other activity you can do.
Most people who have a pacemaker can have an active sex life. After you get a pacemaker implanted, you'll let your chest heal for a short time. If your doctor says that you can exercise and be active, then it's probably safe for you to have sex.
Talk with your doctor if you have any concerns.
As you plan for your future and your end of life, you can include plans for your pacemaker. You can make the decision to turn off your pacemaker as part of the medical treatment that you want at the end of life. You can put this information in your advance directive.
Call your doctor right away if you have symptoms that could mean your device isn't working properly, such as:
Call your doctor right away if you think you have an infection near your device. Signs of an infection include:
It's safe to use a cell phone, but don't keep it in a pocket directly over your pacemaker.
You need to carry a pacemaker ID card with you at all times. The card should include manufacturer information and the model number.
Now that you have read this information, you know more about living with a pacemaker.
If you have questions, take this information with you when you visit your doctor.
