Why the study?
Does vagal modification after segmental pulmonary vein isolation predict late recurrence of paroxysmal atrial fibrillation in patients with PAF?
Does vagal modification after segmental pulmonary vein isolation predict late recurrence of paroxysmal atrial fibrillation in patients with PAF?
Vagal modification, reflected by decreased parasympathetic nervous activity immediately after segmental pulmonary vein isolation, is associated with a lower risk of late paroxysmal atrial fibrillation recurrence.
No takes yet. Share an insight, caveat, or question.
Post-S-PVI HF power may stratify PAF recurrence risk; leaves open whether vagal modification improves ablation outcomes.
Yoshida et al. (2009) studied this question.
