Overview

Recurrent syncope occurs in a minority of paced AVB patients; leaves open predictors and management strategies for prospective evaluation.

Structured PICO

Does permanent pacemaker implantation prevent syncope recurrence in patients with atrioventricular block?

P
Population
229 consecutive patients (mean age 80 ± 10 years, 124 males) who received a permanent pacemaker for atrioventricular block (AVB) with syncope (n=94) or without syncope (n=135).
I
Intervention
Permanent pacemaker implantation
C
Comparator
Comparison between patients with documented AVB plus syncope, undocumented AVB plus syncope, and AVB without syncope
O
Outcome
Actuarial syncope recurrence rate at 5 yearshard clinical

Permanent pacing is highly effective at preventing syncope recurrence in patients with documented AVB, but recurrences are more common when AVB is only suspected or in patients without structural heart disease.
