Feedback:
An electronic pacemaker may be used to provide external stimulus to the heart. The electronic pacemaker stimulates heart contractions by means of wires connected to electrodes, which are inserted into the heart. Clients who experience frequent difficulty with heart contractions may have a permanent pacemaker implanted. The problem may be caused by a lack of initiation of electrical activity (e.g., heart block) or uncontrolled episodes of irregular or paroxysmal cardiac electrical conduction (e.g., assorted cardiac dysrhythmias) in either the atria or ventricles.
