Optimization of nonresponders to left bundle branch area pacing using electrical dyssynchrony mapping

Heart Rhythm O2 2026

Left bundle branch area pacing (LBBAP) is a new approach to resynchronization in patients with heart failure (HF). Treatment of LBBAP nonresponders by optimizing programming has not been studied.

Electrical dyssynchrony mapping and optimization of nonresponders in patients programmed with the adaptive cardiac resynchronization therapy algorithm

Heart Rhythm 2024

The adaptive cardiac resynchronization therapy (CRT) (aCRT) algorithm provides an important clinical benefit. However, a significant number of patients are nonresponders.

CRT optimization in nonresponders and incomplete responders using electrical dyssynchrony mapping

Heart Rhythm 2022

Nonresponse to cardiac resynchronization therapy (CRT) occurs in ∼30%–50% of patients. There are no well-accepted clinical approaches for optimizing CRT in nonresponders.
