Description of intervention(s) / exposure
Treatment: Drugs - Vernakalant Injection
Treatment: Drugs - Amiodarone Injection:

Experimental: 1 - Vernakalant Injection:

In one infusion line, subjects will receive a 10-minute infusion of vernakalant followed by a 15-minute observation period, followed by an additional 10-minute infusion of vernakalant if required (if the subject is still in AF). To maintain blinding, a 60-minute infusion of placebo (D5W) will be administered in a second infusion line, followed by a maintenance infusion of placebo for a minimum of an additional 60 minutes.

Active comparator: 2 - Amiodarone Injection:

In one infusion line subjects will receive a 60-minute infusion of amiodarone followed by a maintenance infusion of amiodarone over an additional 60 minutes. To maintain blinding, a 10-minute infusion of placebo (normal saline) will be administered in a second infusion line, followed by a 15 minute observation period, followed by a 10 minute infusion of placebo if the subject is still in AF.


Treatment: Drugs: Vernakalant Injection
10-minute infusion of 3 mg/kg vernakalant injection followed by a 15-minute observation period, followed by an additional 10-minute infusion of 2 mg/kg of vernakalant if required (if the subject is still in AF).

Treatment: Drugs: Amiodarone Injection:
60-minute infusion of 5 mg/kg amiodarone followed by a maintenance infusion of 50 mg amiodarone over an additional 60 minutes (equivalent to approximately 15 mg/kg over 24 hrs).

Summary
Brief summary
The primary objective of the study is to demonstrate the superiority of vernakalant injection over amiodarone injection in the conversion of atrial fibrillation (AF) to sinus rhythm (SR) within 90 minutes of the start of drug administration. The secondary objective is to compare the safety of vernakalant to amiodarone.
