Rhythm Control Versus Rate Control for New Onset Atrial Fibrillation

Seoul National University Hospital1 enrolled

Overview

Adult patients who are diagnosed new onset atrial fibrillation with rapid ventricular response within 7 days after non-cardiac non-thoracic surgery are enrolled.

After randomization, they are allocated to rhythm control strategy group or rate control strategy group. In rhythm control strategy group, patients are given amiodarone primarily for the purpose of sinus conversion of cardiac rhythm. In rate control strategy group, patients are given diltiazem or esmolol for the purpose of rate control. the rate of sinus conversion within 48 hours after treatment are compared.
