Applying sinus node function testing to evaluate perioperative management for patients suffering from tachycardia‐bradycardia syndrome before atrial fibrillation ablation

Abstract

Abstract Sinus node (SN) function is an important prognostic factor of atrial fibrillation (AF). However, AF ablation guideline has not recommended SN function test before ablation. SN function testing before AF ablation in patients with tachycardia‐bradycardia syndrome should be beneficial to determine further therapy strategies and prognosis.
