Why the study?
Single chamber atrial pacing should suffice for sinus node dysfunction with intact AV conduction, but dual chamber devices are often implanted due to concern for new-onset AV block.
Does single chamber atrial pacemaker implantation provide adequate mode survival without requiring upgrade in patients with sinus node dysfunction and normal AV conduction?
Does single chamber atrial pacemaker implantation provide adequate mode survival without requiring upgrade in patients with sinus node dysfunction and normal AV conduction?
Single chamber atrial pacing is a durable and safe option for relatively young patients with sinus node dysfunction and normal AV conduction, with no patients requiring upgrade to dual-chamber pacing over a mean follow-up of 4 years.
No takes yet. Share an insight, caveat, or question.
Supports AAI pacing durability in SND with intact AV conduction; leaves open need for randomized confirmation before broader adoption.
