There were 29 patients enrolled. 17 (59%) patients were moderate FTR
and 12 (41%) patients were severe FTR at baseline. The paced QRS
duration showed no difference compared to baseline (112.9 ± 13.9 vs
113.8 ± 29.1 ms, P=0.856). The paced HR was 65.4 ± 6.9 bpm, was
significantly higher than that of baseline (46.7 ± 8.0 bpm) (P
<0.001). 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). One
week after LBBAP, 15 (52%) patients had FTR improvement. The mean FTR
degree was decreased from 2.4 ± 0.5 to 1.9 ± 0.7, P<0.001. Six
months after LBBAP, 13 (45%) patients remained with FTR improvement.
The mean FTR degree was decreased from 2.4 ± 0.5 to 2.0 ± 0.8,
P<0.001.
