WONDER QUESTION: I wonder how a pacemaker works?
 * If your heart is off-beat the generator ﻿will send an electric shock though the wire to get your heart back on beat.
 * A pacemaker has a battery, wire, and a generator in a small box.
 * To have a pacemaker implanted, you will get a needle inserted in a large vein by your shoulder.
 * Then they will thread it to the right place and make an incision in your chest.
 * They will slip the small box just under your skin.
 * They will connect the wire to your heart, then the doctor will make sure it works. Then the doctor will stitch up the incision.
