Does catheter ablation along the sinus nodal artery cause reversible sinus node dysfunction in a patient with paroxysmal atrial fibrillation?
Does catheter ablation along the sinus nodal artery cause reversible sinus node dysfunction in a patient with paroxysmal atrial fibrillation?
Multiple ablations along the sinus nodal artery during atrial fibrillation ablation can cause reversible sinus node dysfunction.
Ablations along the sinus nodal artery may cause reversible sinus node dysfunction; this case leaves open questions on procedural risks in paroxysmal AF.
A 60-year-old man who had medically refractory paroxysmal atrial fibrillation (PAF) had undergone catheter ablation. Despite the amiodarone usage, there was no sinus pause lasting more than 2 s after termination of PAF. Amiodarone was discontinued for 4 weeks before ablation. After successful isolation of bilateral pulmonary vein antrum and posterior roof line, sustained atrial tachycardia (AT) …
