Why the study?
Sinus arrest or Torsades de Pointes typically recovers spontaneously within a few hours following ibutilide, making cases with long persistent complications noteworthy.
Does ibutilide cause long persistent sinus arrest and Torsades de pointes in patients undergoing atrial fibrillation ablation?
Does ibutilide cause long persistent sinus arrest and Torsades de pointes in patients undergoing atrial fibrillation ablation?
Ibutilide administration for cardioversion after atrial fibrillation ablation can be associated with severe, long persistent sinus arrest and Torsades de pointes.
Ibutilide may cause prolonged sinus arrest and TdP; case report leaves open need for extended monitoring protocols.
Ibutilide is commonly used for conversion of atrial fibrillation (AF) during catheter ablation procedure. Sinus arrest or Torsades de Pointes (TdP) is mainly complication of ibutilide, however, is recovery spontaneously after a few hours.We present a patient suffering long persistent sinus arrest and Torsades de pointes following administration of ibutilide for cardioversion of persistent AF after radiofrequency ablation.
