Heart rate changes and LBBAP percentage
The VP percentage at one week was 85.9 ± 20.6%, and remained stable during 6 months follow-up (81.0 ± 19.2%) (P=0.159). The paced HR was 65.4 ± 6.9 bpm, which was significantly higher than that of baseline (46.7 ± 8.0 bpm) (P <0.001). The percentage of HR change was 43.5 ± 24.6% (see Table 3). One patient had premature ventricular contraction (PVC) burden of 10.1%. The other patients had relatively low PVC burden (≤2%).
