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

Heart failure (HF) is often accompanied by atrioventricular (AV) conduction disturbance,
represented by prolongation of the PR interval on the electrocardiogram. Studies suggest …

Background Cardiac resynchronization therapy (CRT) reduces morbidity and mortality in
heart failure patients with reduced left ventricular function and intraventricular conduction …

Introduction Fusion of left ventricular pacing with intrinsic conduction provides superior
resynchronization compared to biventricular pacing. His bundle pacing (HBP) preserves …

Aims To determine the prevalence, incidence, predictors, and prognostic implications of PR
interval prolongation in patients referred with suspected heart failure. Methods and results …

Background: Heart failure (HF) patients with wide QRS often benefit from cardiac
resynchronization therapy (CRT), although QRS narrowing does not always occur. The …

On standard electrocardiogram (ECG) PQ interval is known to be moderately heart rate
dependent, but no physiologic details of this dependency have been established. At the …

Background: The benefits of cardiac resynchronization therapy (CRT) in patients with non-
left bundle branch block (LBBB) conduction abnormality have not been fully explored …

Heart failure (HF) is a complex clinical syndrome resulting from structural or functional
impairments of ventricular filling or ejection of blood. HF has a poor prognosis and the …
