Your cardiac device has a pulse generator which includes a battery. The battery life is limited. When the battery gets low, it needs to be changed. In most cases, patients go home the same day.

The Day Before Surgery
A nurse will call you the day before surgery (or the Friday before a Monday surgery). The nurse will review your instructions and tell you what time to arrive. If you do not hear from us by 4 pm, please call: 608-263-1530.

If you feel sick or have a fever over 100°F the day before surgery, call the clinic.

The Day of Surgery
Before the procedure starts blood may be drawn for labs. You will have an IV placed in your hand or arm. If needed, a small area around the surgical sites will be shaved. Your skin will be cleaned with a special soap. You may receive antibiotics through your IV to help prevent infection.

You will receive medicine to make you comfortable. Your skin will be numbed around the incision site.

Sterile drapes will cover you from your neck to your feet so that only the surgical site is exposed.

The Procedure
An incision is made over the pulse generator “pocket”. The leads will be unscrewed. The pulse generator is then removed and a new one is connected to the leads. The new device is then put into the pocket and the incision is closed with dissolvable sutures or surgical glue. The whole process takes about 1-2 hours.

Going Home
You will likely go home the same day. We will review discharge instructions with you.

You cannot drive yourself home. You need to arrange for someone to drive you home. You can resume driving after 24 hours.


  • Avoid dental work for 1 month.

Incision Care
It is important that you take care of your incision to prevent an infection.

  • Keep the site clean and dry.

  • Do not use any lotions or ointments on the incision.

  • Do not scratch or rub the site.

  • Do not soak in a bathtub, hot tub, or go into a pool, lake or river until your incision is completely healed.

  • Leave the current bandage on for 72 hours.

  • Do not shower for _____days.

  • Your incision may have clear glue or small pieces of adhesive tape called “steri-strips” under the bandage. If there are steri-strips in place, leave them until they fall off on their own. The nurse may also remove them at your follow-up visit.

  • When you do shower, let the soap and water run down the incision and gently pat dry.

Look at the site daily for signs of infection.

  • Redness

  • Swelling

  • Fever (101°F or higher)

  • Drainage

  • Tenderness

  • Warm to touch

You may take a mild pain reliever such as acetaminophen (Tylenol®) or ibuprofen (Motrin®) for any pain. You may also apply an ice pack. Ibuprofen or other NSAID medicines increase your risk of bleeding. You may want to avoid them if you are taking a blood thinner.

Device ID Card
You will receive a temporary ID card and will receive your permanent card in about 2 months. Carry your card with you all the time. Tell your health and dental care providers that you have a permanent cardiac device.

Electrical Hazards
You will need to avoid certain types of electrical devices. For more information, call your device company.
