Summary of "Cardiac resynchronization therapy by left bundle branch area pacing in heart failure patients with left bundle branch block."

Cardiac resynchronization therapy (CRT) via bi-ventricular pacing has demonstrated clinical benefits in heart failure (HF) patients with ventricular dyssynchrony. Other approaches of CRT is little known.

Recovery of complete left bundle branch block following heart failure improvement by left bundle branch pacing in a patient.

His bundle pacing (HBP) with a significantly increased electrical output can correct left bundle branch block (LBBB) with potential long-term instability . Recently, among patients with or without LBB...

PR Prolongation Predicts inadequate resynchronization with biventricular pacing in left bundle branch block.

PR interval prolongation is associated with poor outcome after cardiac resynchronization therapy (CRT) among patients with left bundle branch block (LBBB) but the mechanisms are unknown. We investigat...

Prospective Evaluation of Feasibility, Electrophysiologic and Echocardiographic Characteristics of Left Bundle Branch Area Pacing.

His bundle pacing (HBP) is the most physiologic form of pacing but associated with higher thresholds and lower success in patients with His-Purkinje conduction disease. Recent reports have described t...

Differential effect with septal and apical RV pacing on ventricular activation in patients with left bundle branch block assessed by non-invasive electrical imaging and in silico modelling.

It is uncertain whether right ventricular (RV) lead position in cardiac resynchronization therapy impacts response. There has been little detailed analysis of the activation patterns in RV septal paci...

Immediate clinical outcomes of left bundle branch area pacing vs conventional right ventricular pacing.

Left bundle branch area pacing (LBBaP) is a new physiological pacing strategy that produces comparable clinical effects to His bundle pacing (HBP).

Left Bundle Branch Area Pacing in AVB Patients

Right ventricular pacing (RVP) causes left ventricular mechanical dyssynchrony by inducing electrical interventricular and intraventricular dyssynchrony. His bundle pacing may restore the ...

B-Left HF: Biventricular Versus Left Univentricular Pacing With Implantable Cardiac Defibrillator (ICD) Back-Up in Heart Failure Patients

The purpose of this study is to demonstrate that biventricular pacing (BiV) and left univentricular (left ventricular [LV] only) pacing are safe and effective for cardiac resynchronization...

Left Ventricular Septal Pacing: Potential Application for Cardiac Resynchronization Therapy

In cardiac resynchronization therapy (CRT), biventricular pacing is performed by pacing the right ventricle (RV) and epicardium of the left ventricular (LV) postero-lateral wall. A signifi...

Mapping and Pacing of the His Bundle for Heart Failure Patients With Left Bundle Branch Block

This is a prospective, single-arm, non-randomized, non-blinded study designed to characterize the locations of His Bundle (HB) pacing that results in correction of electrical dyssynchrony ...

Prognosis of Patients With Compete Left Bundle Branch Block

The investigators sought to evaluate the morphological and functional changes, risk stratification and prognosis of patients of participants with compete left bundle branch block (CLBBB). ...

Medical and Biotech [MESH] Definitions

The restoration of the sequential order of contraction and relaxation of the HEART ATRIA and HEART VENTRICLES by atrio-biventricular pacing.

Small band of specialized CARDIAC MUSCLE fibers that originates in the ATRIOVENTRICULAR NODE and extends into the membranous part of the interventricular septum. The bundle of His, consisting of the left and the right bundle branches, conducts the electrical impulses to the HEART VENTRICLES in generation of MYOCARDIAL CONTRACTION.

Types of artificial pacemakers with implantable leads to be placed at multiple intracardial sites. They are used to treat various cardiac conduction disturbances which interfere with the timing of contraction of the ventricles. They may or may not include defibrillating electrodes (IMPLANTABLE DEFIBRILLATORS) as well.

An autosomal dominant defect of cardiac conduction that is characterized by an abnormal ST-segment in leads V1-V3 on the ELECTROCARDIOGRAM resembling a right BUNDLE-BRANCH BLOCK; high risk of VENTRICULAR TACHYCARDIA; or VENTRICULAR FIBRILLATION; SYNCOPAL EPISODE; and possible sudden death. This syndrome is linked to mutations of gene encoding the cardiac SODIUM CHANNEL alpha subunit.

A form of heart block in which the electrical stimulation of HEART VENTRICLES is interrupted at either one of the branches of BUNDLE OF HIS thus preventing the simultaneous depolarization of the two ventricles.
