Task: Answer Verification
Input (English): Question: Does acute conversion of persistent atrial fibrillation during dofetilide loading predict long-term atrial fibrillation-free survival?
Answer: Acute pharmacologic conversion of persistent AF/AFl to sinus rhythm frequently occurs during dofetilide loading. Nevertheless, acute pharmacologic conversion does not predict long-term arrhythmia control, which was moderate at best.
Output (English): no
