Estimated battery longevity
The estimated mean battery longevity was significantly shorter with the
MPP strategy (MPP-ON; n = 11) than with the SPP strategy
(MPP-OFF; n = 21), resulting in mean battery longevity estimates of
6.3±2.0 years and 8.1±2.3 years, respectively (P = 0.03). The
mean LV pacing output was 2.7±0.6 V/0.5 ms with the SPP configuration
and was similar to that with the MPP configuration (LV1, 2.5±0.7 V/0.5
ms; LV2, 2.8±0.7). At 45 days post-implantation, the RV and right atrial
thresholds and the percentage of atrial pacing and biventricular pacing
were similar in both groups. Additionally, no differences were found
based on the device type or manufacturer (Table S5 ). No
defibrillator shocks occurred among the entire sample during the 45-day
follow-up period.
