Key result
A longer sinus node recovery time after defibrillation independently predicted atrial fibrillation recurrence after catheter ablation in patients with long-standing persistent atrial fibrillation (adjusted HR 2.13).

A prolonged sinus node recovery time after defibrillation is an independent predictor of long-term atrial fibrillation recurrence following catheter ablation in patients with long-standing persistent AF.

May aid post-ablation risk stratification in long-standing persistent AF; leaves open whether sinus node recovery time should guide ablation strategies.
Yamaguchi et al. (2018) conducted a cohort in Long-standing persistent atrial fibrillation (n=51). Longer sinus node recovery time (SNRT) after defibrillation vs. Shorter SNRT was evaluated on Atrial fibrillation recurrence after ablation (HR 2.13, 95% CI 1.16-3.71, p=0.0152). A longer sinus node recovery time after defibrillation independently predicted atrial fibrillation recurrence after catheter ablation in patients with long-standing persistent atrial fibrillation (adjusted HR 2.13).
