Does acute conversion of persistent atrial fibrillation during dofetilide loading predict long-term atrial fibrillation-free survival?
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.
Over ten years, screening reduced mortality from AAA by 73%, and the frequency of emergency operations by 68%.
