Reasons for Procedure
- The body's natural pacemaker, the sinoatrial (SA) node, is not working properly—this can cause the heart to beat too slowly
- There are malfunctions in the atrioventricular (AV) node, which is the part of the heart’s electrical system that sends signals from the SA node to the ventricles—this leads to a slow heartbeat
- Heart performance in people with severe symptoms of congestive heart failure and a weakened heart muscle, known as cardiomyopathy, needs to be improved—his is called biventricular pacing, or cardiac resynchronization therapy
- Cardiac surgery is being done
- Excess bleeding
- Pacemaker malfunction
- Inappropriate stimulation of the diaphragm, which is the large muscle between chest and abdominal cavities
- Rupture in the heart muscle—rare
- History of smoking
- History of excess alcohol consumption
- Bleeding or blood-clotting irregularities
- Regular use of some medications
- Chronic disease
What to Expect
Prior to Procedure
- Blood tests
- Chest x-rays—to look at the heart's structure
- Electrocardiogram (EKG)— to record the heart's activity
- Talk to your doctor about your medications. You may be asked to stop taking some medications up to 1 week before the procedure.
- Eat a light meal the night before the procedure. Do not eat or drink anything after midnight.

How Long Will It Take?
How Much Will It Hurt?
- Avoid strenuous activity, especially involving the upper body, for 4-6 weeks.
- Avoid excessive movement of the arm/shoulder on the side of the pacemaker for 2 weeks. This will help you to avoid dislodging the leads. You may be given a sling to wear to help remind you.
Now that you have a pacemaker,
you may need to avoid:
- MRI scans
- Heat therapy—often used in physical therapy
- High-voltage or radar machinery such as electric arc welders, high-tension wires, radar installations, or smelting furnaces
- Contact with radio or television transmitters
- Do not carry a cell phone in a pocket directly over the device. Keep the phone on the side away from the device. Headphones worn with MP3 players may also cause interference.
- Turn off car or boat motors when working on them. They may confuse your device.
- Tell your doctors and dentist that you have a pacemaker.
- Check with your doctor about the safety of going through airport security detectors with your device.
- Be sure to follow your doctor's instructions.
