Enrollment: 0
Study Start Date: September 2012
Estimated Study Completion Date: March 2016
Estimated Primary Completion Date: February 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Vernakalant Drug: Vernakalant
Initial intravenous (IV) dose of 3 mg/kg (up to a maximum of 339 mg) over 10 minutes, followed by a 15 minute observation period and, if conversion to sinus rhythm does not occur within 15 minutes of the initial infusion, a second 10 minute infusion of vernakalant at a dose of 2 mg/kg (up to a maximum of 226 mg) will be administered.
