Anatomical Ablation of the Atrioventricular Node [PDF]
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.

The Anatomy of the Atrioventricular Node [PDF]
The anatomical arrangement of the atrioventricular node has been likened to a riddle wrapped up in an enigma. There are several reasons for this alleged mystery, not least the marked variability in structure between different species.

Inferior Extensions of the Atrioventricular Node [PDF]
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 ...

Ultrastructure of the Human Atrioventricular Node [PDF]
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 ...

HCN4 in the atrioventricular node
Hyperpolarization-activated cyclic nucleotide-gated channel 4 (HCN4) drives the funny current in cardiac pacemaker regions. Its involvement in sinoatrial node pacemaker generation is well known, but its function in the atrioventricular (AV) node (AVN) has not intensively been studied.

Connexins and the atrioventricular node
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 4 different connexin isoforms with single channel conductances ranging from ultralow to high ...

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
