There are two wires for Atrial Pacing and two wires for Ventricular Pacing. If the surgeon only wants A-pacing, there will be two wires on the right side of the chest below the midsternal incision; AV-pacing will have 4 wires, 2 on the right and 2 on the left; V pacing will have two wires on the left. Wires are sometimes color-coded depending on surgeon preference (A wires are sometimes orange - the color coding is not only beneficial for identification but also has a shorter wire that is implanted on the epicardium since the atrial wall is thinner). All wires are sutured into the epicardium during surgery, they have a needle in the end of them when the package is opened and the surgeon sutures the wire in place on the epicardium and out through the chest wall eventually exiting out to the skin then snips the needle off once the wires are in place. They are looped outside of the skin, sutured in place with stitches for extra protection from being accidentally pulled.
