Randomized Controlled Trial Clinical TrialEffects of oral propafenone administration before electrical cardioversion of chronic atrial fibrillation: a placebo-controlled study.
Our aim was to evaluate the benefits and risks of administering propafenone before electrical defibrillation for chronic atrial fibrillation. ⋯ Propafenone, given before electrical cardioversion for chronic atrial fibrillation does not affect the mean defibrillation threshold or the rate of successful arrhythmia conversion. It decreases the recurrence of atrial fibrillation early after shock, thus allowing more patients to be discharged from the hospital with sinus rhythm.
