Cardiac pacing is an effective treatment for patients with bradycardia due to sinus node
dysfunction or atrioventricular block. Despite decades of technological advances, the …

Cardiac resynchronization therapy (CRT) was proposed in the 1990s as a new therapy for
patients with heart failure and wide QRS with depressed left ventricular ejection fraction …

Background Continuous automatic optimisation of cardiac resynchronisation therapy (CRT),
stimulating only the left ventricle to fuse with intrinsic right bundle conduction (synchronised …

Abstract Background His-Purkinje conduction system pacing (HPCSP) using His bundle
pacing (HBP) or left bundle branch pacing (LBBP) has emerged as an alternative to …

Objectives This study sought to evaluate the effectiveness of His-optimized cardiac
resynchronization therapy (HOT-CRT) for reducing left ventricular activation time (LVAT) …

Aims Although cardiac resynchronization therapy (CRT) is effective in patients with systolic
heart failure (HF) and a wide QRS interval, a substantial proportion of patients remain non …

Introduction Cardiac resynchronization therapy (CRT) reduces heart failure (HF)
hospitalization and all‐cause mortality in HF patients with left bundle branch block (LBBB) …

Background QRS narrowing following cardiac resynchronization therapy with biventricular
(BiV) or left ventricular (LV) pacing is likely affected by patient‐specific conduction …

In chronic systolic heart failure and conduction system disease, cardiac resynchronization
therapy (CRT) is the only known non-pharmacologic heart failure therapy that improves …

The time point after CRT implantation to evaluate patients is important. Too early an
assessment may underestimate the degree of reverse remodeling. Most studies (Table) …
