Background: Patients (pts) with atrial fibrillation (AF) often have insertable cardiac monitors (ICM) placed in order to monitor AF burden. The purpose of this study was to determine the incidence of pauses detected by ICM in pts with AF but without prior syncope or related symptoms (syncope) that would meet ACC/AHA guidelines for pacemaker (PM) implantation.
Methods: 75 consecutive pts with AF and without syncope who underwent ICM implantation were enrolled in this study. Date were collected and analyzed from a prospectively maintained database, with retrospective chart review, as required.
Results: The mean age (years), BMI (kg/m2), and EF (%) were 62.2 ± 11.5, 29.1 ± 6.1, and 0.59 ± 0.07, respectively.
Among the 75 pts, 11 (15%) had a pause detected on ICM which met AHA/ACC guidelines for PM implant, and 8 (11%) underwent PM implant. The mean pause was 6.4 ± 3.8 seconds and the time from ICM implant to pause detection was 33 ± 47 days. Six of 11 (55%) pts with pauses had offset pauses, while pauses during sinus (4 pts) and AF (1 pts) were also observed. Pts with pauses had greater AF burden, pulmonary arterial (PA) pressure, and CHA2DS2-VASc score, and lower statin use (Table).
Conclusions: 15% of patients with AF but without syncope or related symptoms had pauses detected by ICM which required PM implantation. Patients with pauses requiring PM implant had higher AF burden, PA pressure, and CHA2DS2-VASc score, and lower statin use.
