Pacemaker programming in patients with first-degree AV-block: Programming pattern and possible consequences.

Background: The optimal way of pacing in patients with an indication for pacing and concomitant first-degree atrioventricular (AV)-block is not known, and consequently, firm guidelines on this topic are lacking. This study explored the current pacemaker programming pattern in patients with first-degree AV-block who have a dual chamber pacemaker without cardiac resynchronization.

Methods: The study was a retrospective chart review conducted at Duke University Hospital.
