Short-term effect of low atrial septum pacing on new-onset atrial fibrillation in patients with sinus node dysfunction a prospective randomized single-center study

For patients with SND after dual-chamber pacemaker implantation, AF incidence within 1 year after LAS pacing was significantly lower than that after RAA pacing. LAS pacing could shorten the postoperative P-wave duration, an independent risk factor for new-onset AF, and LAS pacing effectively reduced the Cum % VP, which may be the underlying mechanism by which LAS pacing prevents postoperative AF occurrence.
