Placing a pacemaker requires minor surgery. The surgery usually is done in a hospital or special heart treatment laboratory.
Before the surgery, an intravenous (IV) line will be inserted into one of your veins. You will receive medicine through the IV line to help you relax. The medicine also might make you sleepy.
Your doctor will numb the area where he or she will put the pacemaker so you don't feel any pain. Your doctor also may give you antibiotics to prevent infection.
First, your doctor will insert a needle into a large vein, usually near the shoulder opposite your dominant hand. Your doctor will then use the needle to thread the pacemaker wires into the vein and to correctly place them in your heart.
An x-ray "movie" of the wires as they pass through your vein and into your heart will help your doctor place them. Once the wires are in place, your doctor will make a small cut into the skin of your chest or abdomen.
He or she will slip the pacemaker's small metal box through the cut, place it just under your skin, and connect it to the wires that lead to your heart. The box contains the pacemaker's battery and generator.
Once the pacemaker is in place, your doctor will test it to make sure it works properly. He or she will then sew up the cut. The entire surgery takes a few hours.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans.
