Anatomical Ablation of the Atrioventricular Node [PDF]

Arrhythmia & Electrophysiology Review
Background: Atrioventricular (AV) conduction ablation has been achieved by targeting the area of penetration of the conduction axis as defined by recording a His bundle potential.

Inferior Extensions of the Atrioventricular Node [PDF]

Arrhythmia & Electrophysiology Review, 2021
The pathways for excitation of the atrioventricular node enter either superiorly, as the so-called ‘fast’ pathway, or inferiorly as the ‘slow’ pathway. However, knowledge of the specific anatomical details of these pathways is limited. Most of the experimental studies that established the existence of these pathways were conducted in mammalian hearts ...

Connexins and the atrioventricular node [PDF]

Heart Rhythm, 2013
The structure and functioning of the atrioventricular (AV) node has remained mysterious owing to its high degree of complexity. In this review article, we integrate advances in knowledge regarding connexin expression in the AV node. Complex patterning of

Ultrastructure of the Human Atrioventricular Node [PDF]

Circulation, 1968
Ultrastructure of the A-V node was studied in two human hearts. Fine details of intranodal cellular organization were then resynthesized on the basis of light microscopic examinations of over 250 human hearts. There are four different types of cells and no anatomic syncytium in the human A-V node: (1) a simple rounded cell identical to P cells of the ...

Feasibility and Efficacy of His Bundle Pacing or Left Bundle Pacing Combined With Atrioventricular Node Ablation in Patients With Persistent Atrial Fibrillation and Implantable Cardioverter‐Defibrillator Therapy

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Persistent atrial fibrillation may lead to a higher probability of inappropriate shocks in heart failure patients with an implantable cardioverter‐defibrillator (ICD). The aim of this study was to evaluate the impact of His‐Purkinje conduction

Benefits of Permanent His Bundle Pacing Combined With Atrioventricular Node Ablation in Atrial Fibrillation Patients With Heart Failure With Both Preserved and Reduced Left Ventricular Ejection Fraction

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundClinical benefits from His bundle pacing (HBP) in heart failure patients with preserved and reduced left ventricular ejection fraction are still inconclusive.
