What is involved in putting a pacemaker in?

Pacemaker Implant: A pacemaker is about the size of a small pager, but 1/2 as thick. It's implanted, under the skin, through a small incision, just under the collar bone. Two wires are threaded through a vein that travels under the collar bone. The wires follow vein back to your heart. Procedure takes about an hour and overnight hospital stay is common. Mild sedatives are and local pain control is usually used.
