A pacemaker is a device that administers electrical energy to the heart to stimulate contraction and regulate its rhythm. Pacemakers may be permanent or temporary (e.g. transcutaneous, transvenous or epicardial wires).The essential components of a pacemaker are: 1  Pulse generator (the power source).nd letter: Chamber sensed â dual chamber (atrial and ventricle). 3rd letter: Pacemaker response to a sensed event â dual response (can trigger or inhibit). Thus a pacemaker functioning in DDD mode can pace either or both the atria and ventricles.
