Pacemakers and implantable cardioverter-defibrillators (ICDs) are battery-powered devices that are implanted in the body to treat heart rhythm problems. Your device is placed beneath the skin of your chest. One to three wires (called leads) connect the device to your heart. When the battery runs down, or if the device isn't working well, you may choose to have the device replaced.
The leads can be left in place and reconnected to your new device. But if your doctor thinks you need new leads, the doctor can replace them at the same time.
You will get medicine before the procedure. This helps you relax and helps prevent pain. You may also get an antibiotic to help prevent infection. The doctor will make a cut in the skin next to your device. The doctor will remove the device and put a new one in its place. The doctor will then attach the leads to the device. The cut will be closed with stitches, tape, or a special glue.
The procedure usually takes about an hour. You may go home the same day. If the leads were replaced, you may need to spend the night in the hospital.
Surgery can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for surgery.

Pacemaker or ICD replacement is surgery to put a new heart device in your chest. The battery in your new device is fully charged. Your doctor may have also replaced the wires (leads) from the device to your heart, if needed.
Your chest may be sore where the doctor made the cut (incision) and put in the device. You also may have a bruise and mild swelling. These symptoms usually get better in 1 to 2 weeks. You may feel a hard ridge along the incision. This usually gets softer in the months after surgery. You may be able to see or feel the outline of the device under your skin.
You may be able to go back to work or your usual routine within 1 week after surgery. It may take as long as 2 weeks if your leads were also replaced.
