pacemaker  (psmkr)

1. Any of several usually miniaturized and surgically implanted electronic devices used to stimulate or regulate contractions of the heart muscle. Electrodes attached to the heart muscle conduct electrical signals generated from the pacemaker, which either provides constant electrical stimuli to regularize the heartbeat (fixed-rate pacemakers) or provides a stimulus only when electrical activity within the heart is abnormal (demand pacemakers). Pacemakers are used in the treatment of various arrhythmias.

2. A part of the body, such as the specialized mass of cardiac muscle fibers of the sinoatrial node, that sets the pace or rhythm of physiological activity.
