Implantable cardioverter-defibrillator

An implantable cardioverter-defibrillator is a device that doctors put inside your body if you have a heart problem. It's like a little computer that helps your heart beat normally.

The device has two parts: the first part is a small box that the doctors put under the skin on your chest. This box has some wires that go into your heart to help it beat.

The second part is like a watch that you wear around your wrist. It talks to the box under your skin and makes sure your heart is beating the way it should.

If your heart starts beating too fast or too irregularly, the device will send a little electric shock to your heart to make it beat normally again.

It's like a superhero that helps keep your heart healthy and strong!
