'''Cardioversion''' is a [[medical procedure]] by which an abnormally fast [[heart rate]] ([[tachycardia]]) or other [[cardiac arrhythmia]] is converted to a [[sinus rhythm|normal rhythm]] using [[electricity]] or [[pharmaceutical drug|drugs]]. 

'''Synchronized electrical cardioversion''' uses a therapeutic dose of [[electric current]] to the [[heart]] at a specific moment in the [[cardiac cycle]], restoring the activity of the [[electrical conduction system of the heart]]. ([[Defibrillation#Relationship to cardioversion|Defibrillation]] uses a therapeutic dose of [[electric current]] to the [[heart]] at a random moment in the [[cardiac cycle]], and is the most effective resuscitation measure for [[cardiac arrest]] associated with [[ventricular fibrillation]] and pulseless [[ventricular tachycardia]].<ref>{{cite book| vauthors = Marino PL |title=Marino's the ICU book|date=2014|publisher=Wolters Kluwer Health/Lippincott Williams & Wilkins |isbn=978-1451121186|edition=Fourth}}</ref>) '''Pharmacologic cardioversion''', also called '''chemical cardioversion''',  uses [[Antiarrhythmic agent|antiarrhythmia medication]] instead of an electrical shock.<ref name='Shea2002'>{{cite journal | vauthors = Shea JB, Maisel WH | title = Cardiology patient pages.
