Key result
Bipolar anodal septal pacing with direct LBB capture linked to improved ventricular dyssynchrony versus unipolar nonselective LBBP.
Why the study?
LBBP produces delayed, unphysiological activation of the right ventricle, prompting exploration of whether bipolar anodal septal pacing with direct LBB capture affects ventricular depolarization patterns.
Does bipolar anodal septal pacing with direct LBB capture improve ventricular electrical dyssynchrony compared to unipolar nonselective LBBP in patients with bradycardia?
Observational (n=116)
No

Absolute Event Rate: -9% vs -24%
p-value: p=<0.001
Bipolar anodal septal pacing with direct LBB capture improves ventricular synchrony compared to unipolar nonselective LBBP, though it remains less physiological than His bundle pacing.
No takes yet. Share an insight, caveat, or question.
May support refined LBBP technique in bradycardia; hypothesis-generating and requires RCTs before practice change.
Čurila et al. (2023) conducted an observational in Bradycardia (n=116). Bipolar anodal septal pacing with direct LBB capture (aLBBP) vs. Unipolar nonselective left bundle branch pacing (nsLBBP) was evaluated on Ventricular dyssynchrony (e-DYS) (p=<0.001). Bipolar anodal septal pacing with direct left bundle branch capture significantly improved ventricular dyssynchrony compared to unipolar nonselective left bundle branch pacing (-9 ms vs -24 ms, p<0.001).
