Electrical Cardioversion - Atrial fibrillation
Electrical Cardioversion By Hans R. Larsen MSc ChE Background Cardioversion is used to convert a patient experiencing highly symptomatic or persistent Atrial fibrillation (AF) to normal sinus rhythm (NSR). Conversion can sometimes be achieved by the infusion of drugs like ibutilide (Covert), dofetilide (Tikosyn) or flecainide (Tambocor) in a hospital setting (chemical conversion). Chemical conversion is most effective if started within a couple of hours of the onset of the episode and becomes less effective as time goes by. In cases where an episode has lasted longer than 7 days drug-induced conversion is not effective and Electrical conversion ( Cardioversion ) must be used to regain NSR, either alone or in combination with antiarrhythmic drugs.
action is restored and may result in an ischemic stroke or transient ischemic attack (TIA) usually within the first 10 days following cardioversion.
