Randomized Controlled Trial Comparative Study Clinical Trial
Long-term prevention of atrial fibrillation after coronary artery bypass surgery: comparison of quinidine, verapamil, and amiodarone in maintaining sinus rhythm.
To evaluate the necessity and efficacy of quinidine fumarate, verapimil, or amiodarone prophylaxis for sinus rhythm maintenance in patients who experienced atrial fibrillation after coronary artery bypass surgery. ⋯ There were no significant differences in the maintenance of sinus rhythm among the four groups, so we suggest that long-term prevention of atrial fibrillation in patients with coronary artery bypass grafting was not necessary at the postdischarge period.
