Why the study?
Does left bundle branch pacing improve electrocardiogram characteristics and pacing parameters compared to conventional right ventricular pacing in pacing-indicated patients?
Population
40 pacing-indicated patients prospectively enrolled
Comparison
Left bundle branch pacing achieved by… vs Conventional right ventricular pacing (RVP)
Design
Cohort
Follow-up
3-month
Key result
Left bundle branch pacing produced a significantly narrower paced QRS duration compared to right ventricular pacing (111.85 ms vs 160.15 ms; P<0.001) with low and stable pacing thresholds.

May support LBBP feasibility for narrower QRS in pacing patients; leaves open outcome benefits versus RVP in randomized trials.

Absolute Event Rate: 111.85% vs 160.15%
p-value: p=<0.001
Left bundle branch pacing is clinically feasible, maintains low pacing thresholds, and produces a narrower QRS duration compared to conventional right ventricular pacing.
Chen et al. (2018) conducted a cohort in Pacing-indicated patients (n=40). Left bundle branch pacing (LBBP) vs. Right ventricular pacing (RVP) was evaluated on Paced QRS duration (p=<0.001). Left bundle branch pacing produced a significantly narrower paced QRS duration compared to right ventricular pacing (111.85 ms vs 160.15 ms; P<0.001) with low and stable pacing thresholds.
