I'm 27 now, and I had my pacemaker implanted in 2002. Its not a bad surgery, I was awake for mine. They gave me some medication to help me relax, and a local anesthesia. I could feel some pressure and stuff while they were actually doing the implant, but it wasn't painful. I stayed overnight one night in the hospital, and then was released the next evening. Recovery was fine...my incision was a little sore and tender, but nothing I couldn't handle.
