Graphical Abstract Graphical Abstract Visualization of ventricular activation sequence by using an ultra-high-frequency ECG in heart failure patient with LBBB and LV ejection fraction of 32% (A). LBBB was corrected by LVSP (B), and nsLBBP (C). Both LVSP and nsLBBP corrected right-to-left ventricular dyssynchrony present during LBBB (e-DYS 93 ms). They led to left-to-right ventricular activation pattern, with e-DYS—20 ms during LVSP and—41 during nsLBBP. e-DYS, time difference between the first and last UHF-ECG activation; for more details, see Jurak et al.12 LVSP, left septal myocardial pacing.
Čurila et al. (2023) studied this question. Left bundle branch area pacing capture type was evaluated for its impact on left ventricular resynchronization, though specific results were not provided in the abstract.
