Randomized Controlled Trial Clinical TrialAmiodarone prophylaxis for tachycardias after coronary artery surgery: a randomised, double blind, placebo controlled trial.
Arrhythmias are a common cause of morbidity after cardiac surgery. This study assessed the efficacy of prophylactic amiodarone in reducing the incidence of atrial fibrillation or flutter and ventricular arrhythmias after coronary artery surgery. ⋯ The incidence of clinically significant tachycardia was reduced by amiodarone. The ventricular response rate was slowed in supraventricular tachycardia, but the induction of bradycardia may preclude the routine use of amiodarone for prophylaxis.
