An implantable cardioverter defibrillator (ICD) is a small, battery-operated device. It helps the heart beat normally. ICD implantation is surgery to put an ICD into the chest.
This procedure is done to correct certain abnormal heartbeats such as:
In some people, abnormal heartbeats can raise the risk of cardiac arrest or sudden death. An implanted ICD can help prevent this.

After the ICD is in place, it will need to be tested. General anesthesia will be used for this step. You will be asleep.
The area where the ICD is to be implanted will be cleaned. A small incision will be made below the collarbone.
A wire, called a lead, will be threaded through a vein in the upper chest to the heart. X-rays will be used to watch the lead move through the vein to the heart. The signals between the heart and the ICD will be carried on this lead.
A pocket is made in the incision area. The ICD will be implanted into the pocket.
Once in place, the ICD will be tested. This is to make sure it shocks the heart properly. Precautions will be taken to make sure this is a safe process. When the ICD is working properly and in the right place, the incision will be stitched up. A bandage will be placed over the site.
About 1 to 3 hours
Some pain and stiffness around the area is common for a while.. Medicines and home care help.
