Cardiac pacemakers are effective treatments for a variety of bradyarrhythmias. By providing an appropriate heart rate and heart rate response, cardiac pacing can reestablish effective circulation and more normal hemodynamics that are compromised by a slow heart rate.

This topic will present a broad review of the role of cardiac pacing in a variety of settings. The management of the specific disorders is discussed separately as is a description of the different types of pacemakers and pacing modes. (See "Treatment of the sick sinus syndrome" and "Third degree (complete) atrioventricular block" and "Second degree atrioventricular block: Mobitz type II" and "Modes of cardiac pacing: Nomenclature and selection".)


Despite the myriad of clinical situations in which permanent pacing is considered, most management decisions regarding permanent pacemaker implantation are driven by the following clinical factors:

The association of symptoms with a bradyarrhythmia

The location of the conduction abnormality
