Study Arms:
- electrical cardioversion (Type: EXPERIMENTAL): Patients were sedated with propofol and external cardioversion was performed in anteroposterior position (right sternal body at the third intercostal space-angle of the left scapula). Patients were submitted to a biphasic wave-form sequential shock of 100-150-200 J, if necessary.
- propafenone (Type: ACTIVE_COMPARATOR): Propafenone (2 mg/kg bolus) was administered iv to obtain pharmacologic sinus rhythm conversion.

Based on this trial design, predict the completion outcome and termination type (if applicable).
