Implantable Cardioverter-Defibrillator (ICD) - Topic Overview

How is an ICD placed? continued...

Your doctor makes a small cut (incision) in your upper chest. He or she puts one or two leads (wires) in a vein and threads them to the heart. Then your doctor connects the leads to the ICD. Your doctor programs the ICD and then puts it in your chest and closes the incision.

In some cases, the doctor may be able to put the ICD in another place in the chest so that you don't have a scar on your upper chest. This would allow you to wear clothing with a lower neckline and still keep the scar covered.

Most people spend the night in the hospital, just to make sure that the device is working and that there are no problems from the surgery.

You may be able to see a little bump under the skin where the ICD is placed.

How does it feel to get a shock from an ICD?

The shock from an ICD hurts briefly. It's been described as feeling like a punch in the chest. But the shock is a sign that the ICD is doing its job to keep your heart beating. You won't feel any pain if the ICD uses electrical pulses to fix a heart rate that is too fast or too slow.

There's no way to know how often a shock might occur. It might never happen.

It's possible that the ICD could shock your heart when it shouldn't. You also might be afraid or worried about when the ICD might shock you again. But you can take simple steps to feel better about having an ICD. These include having your ICD checked regularly by your doctor and making an action plan for what to do if you get shocked.

How do I live a normal, healthy life with an ICD?

You can live a normal, healthy life with your ICD. A few tips for living well with your ICD include:

  • Avoid strong magnetic and electrical fields. These can keep your device from working right. Most office equipment and home appliances are safe to use. Learn which things you should use with caution and which you should stay away from.
  • Know what to do when you get a shock from your ICD.
  • Be sure that any doctor, dentist, or other health professional you see knows that you have an ICD.
  • Always carry a card in your wallet that tells what kind of device you have. Wear medical alert jewelry that says you have an ICD.
  • Have your ICD checked regularly to make sure it's working right.
  • It's common to be anxious that the ICD might shock you. But you can take steps to think positively and worry less about living with an ICD.
