Early evaluation of atrial high rate episodes using remote monitoring in pacemaker patients: Results from the RAPID study

Abstract

Aim: Remote monitoring (RM) of implantable cardiac devices has enabled continuous surveillance of atrial high rate episodes (AHREs) with well-recognized clinical benefits. We aimed to add evidence on the role of the RM as compared to conventional follow-up by investigating the interval from AHRE onset to physician’s evaluation and reaction time in actionable episodes. Methods and Results: A total of 97 dual-chamber pacemaker recipients were followed with RM (RM-ON group; N = 64) or conventional in-office visits (RM-OFF group; N = 33) for 18 months. In-office visits were scheduled at 1, 6, 12, and 18 months in the RM-OFF group and at 1 and 18 months in the RM-ON group. The overall AHRE rate was 1.98 per patient-year (95% confidence interval [CI], 1.76–2.20) with no difference between the two groups (RM-ON vs. RM-OFF weighted-HR, 0.88; CI, 0.36–2.13; p =.78). In the RM-ON group, 100% AHREs evaluated within 11 days from onset, and within 202 days in the RM-OFF group, with a median evaluation delay 79 days shorter in the RM-ON group versus the RM-OFF group (p
