Key result
PVI for PAF linked to acute SND requiring urgent pacemakers in 5 cases.
Why the study?
Can pulmonary vein isolation for paroxysmal atrial fibrillation cause acute or sub-acute sinus node dysfunction?
Case Report (n=6)
Can pulmonary vein isolation for paroxysmal atrial fibrillation cause acute or sub-acute sinus node dysfunction?
AF ablation may be complicated by acute or sub-acute sinus node dysfunction, potentially due to thermal injury to the sinus node artery, sometimes requiring pacemaker implantation.

May alert clinicians to rare post-PVI sinus node dysfunction; hypothesis-generating case series that leaves incidence and causality open.
Barra et al. (2018) conducted a case report in Paroxysmal atrial fibrillation (n=6). Pulmonary vein isolation (AF ablation) was evaluated on Acute and sub-acute sinus node dysfunction. Pulmonary vein isolation for paroxysmal atrial fibrillation was associated with acute or sub-acute sinus node dysfunction, requiring urgent pacemaker implantation in 5 of 6 patients.
