Background: Left bundle branch pacing (LBBP) has emerged as a safe and effective alternative to right ventricular pacing. Traditionally, LBBP is performed with lumenless lead (LLL); however, the use of stylet-driven lead (SDL) is on rise. We aimed to assess acute success and procedural outcomes of SDL versus LLL for LBBP.

- During left bundle branch area pacing (LBBAP), the shape of the paced QRS complex can change based on where the pacing occurs, and its relation to patient outcomes is not fully understood.
- This study involved 59 heart failure patients with nonischemic cardiomyopathy, assessing how variations in the QRS morphology influenced their heart function, particularly the left ventricular ejection fraction (LVEF).
- Key findings showed that specific QRS morphologies (qR type) and certain pacing test results were linked to improved heart function, while a prolonged R-wave peak time did not effectively predict outcomes; nonresponsive patients often experienced more severe changes in their QRS readings over time.
Background: Endocardial electrogram (EGM) characteristics in nonischemic cardiomyopathy (NICM) have not been explored adequately for prognostication.
Objective: We aimed to study correlation of bipolar and unipolar EGM characteristics with left ventricular ejection fraction (LVEF) and ventricular tachycardia (VT) in NICM.
Methods: Electroanatomic mapping of the left ventricle was performed.
