The recognition of proper and improper function of implanted electronic pacemakers utilized for cardiac stimulation may be aided by a knowledge of how they function and their effect on the electrocardiographic tracing. The electrocardiograms of patients with fixed rate, demand, atrial synchronous, and ventricular synchronous pacemakers are described. Pacemaker malfunction may arise at a number of points within the pacemaker itself or from failure of the electrical impulse to be conducted to the myocardium. Careful analysis of the electrocardiographic patterns may permit an accurate diagnosis of pacemaker malfunction even before symptoms develop. Electrocardiographic examples are analyzed and discussed.
