The impact of left bundle branch block (LBBB) on cardiac mechanical function ranges from
minimal effect in some patients to marked reduction in left ventricular (LV) systolic function in …

Idiopathic or iatrogenic left bundle branch block (LBBB) is a unique model of electro-
mechanical ventricular dyssynchrony with concordant changes in electrical activation …

Background: Patients with left bundle branch block (LBBB) often respond to cardiac
resynchronization therapy (CRT) with left ventricular ejection fraction (LVEF) improvement …

Background Left bundle branch block (LBBB) represents a frequently encountered
conduction system disorder. Despite its widespread occurrence, a continual dilemma …

Objectives This study speculated that longitudinal strain curves in left bundle branch block
(LBBB) could be shaped by the degree of LBBB-induced cardiac remodeling. Background …

With the emergence of cardiac resynchronization therapy (CRT) as a powerful tool to
reverse left ventricular dysfunction in patients with left bundle branch block (LBBB), there is …

Background Left bundle branch area pacing includes left bundle branch pacing (LBBP) and
left ventricular septal pacing (LVSP), which is effective in patients with dyssynchronous heart …

Background Chronic left bundle branch block (LBBB) can lead to LBBB‐mediated
cardiomyopathy from left ventricular dysynchrony. His‐bundle pacing (HBP) results in direct …

Aims In patients with chronic heart failure, QRS duration is a consistent predictor of poor
outcomes. It has been suggested that for indicated patients, cardiac resynchronization …

Background Left bundle branch block (LBBB) and left ventricular (LV) dyssynchrony likely
contribute to progressive systolic dysfunction. The evaluation of newly recognized LBBB …
