Implication

Coronary sinus ostium positioning was associated with higher FFRWO; hypothesis-generating for lead selection in DDDRP pacemakers pending confirmatory trials.

Structured PICO

Does atrial pacing site and lead tip to ring spacing affect the incidence of far-field R wave oversensing in patients with DDDRP pacemakers?

Population

395 patients implanted with a DDDRP pacemaker designed to diagnose and treat atrial tachyarrhythmias and programmed with a fixed and short postventricular blanking period

Intervention

Different atrial pacing sites (right atrium appendage [RAA], coronary sinus ostium [CSO], lateral wall [LW]) and lead tip to ring spacing (TTRS)

Outcome

Incidence of clinically significant far-field R wave oversensing (FFRWO) inducing inappropriate detection or pacemaker malfunctioningsafety

In DDDRP pacemakers, far-field R wave oversensing is infrequent but more common with coronary sinus ostium lead placement and longer tip-to-ring spacing.
