Atrial Fibrillation
Conditions
Brief summary
This study will compare vernakalant therapy to amiodarone therapy in the acute management of recent onset atrial fibrillation.
Interventions
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.
Administered IV as per product label
