WebPacing counters significantly overestimated the amount of effective BiV pacing, which leads to a wrong perception of the therapy success. Since the results, of the MADIT-CRT trial, we have some important insight on the CRT response in different kinds of LBBB morphology [ 15 ]. WebJun 1, 2024 · We describe a unique case of suboptimal biventricular pacing and our approach to overcome it. 1 INTRODUCTION Studies have shown that biventricular pacing of ≥97% 1 was associated with reduction in recurrent hospitalisation rate and all-cause mortality in patients with systolic heart failure.

WebOct 1, 2024 · Recent studies have demonstrated that His bundle pacing (HBP) can correct LBBB, achieve physiological pacing and realize the cardiac resynchronization. But HBP has high technical requirements, lower sense value and higher threshold of correcting LBBB, which may be further increased in long-term follow-up. ... Paced QRS morphology of … WebThe objective of this study is to demonstrate that individually optimized, triple-site biventricular pacing is superior to standard biventricular pacing in reverse ventricular modeling without increasing the risk of serious procedure- and/or device-related events at 30 days. About 300 patients with non-LBBB morphology will be included in the study.
