The function of a pacemaker is to provide a cardiac rhythm that maintains a cardiac output adequate for normal activity, and in extreme situations, an output compatible with life. As such, a pacemaker may be required for maintenance of a normal cardiac output in patients with chronic or repetitive disorders of cardiac rhythm that cause a lethally low cardiac output. These disorders may be either temporary or permanent.
