How is the procedure done?

• This insertion site, either the chest wall or the abdomen, is numbed and a small pocket is made
• Another incision is made in the vein just under the collarbone through which the wires of the ICD are passed and attached to the inner surface of the heart.
• The other ends of the wires are connected to the main box of the ICD (containing the generator), which is inserted into the pocket created.
• The ICD is tested for good response several times by causing the heart to fibrillate after which the incision is closed
