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 ...

Inferior Extensions of the Atrioventricular Node
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 ...

Mesothelioma of the atrioventricular node. [PDF]
Heart, 1985 A patient with Mobitz type 2 heart block caused by a mesothelioma of the atrioventricular node died of a subarachnoid haemorrhage at the age of 33 two years after implantation of a permanent pacemaker. Mesothelioma of the atrioventricular node is rare, and reported cases have all been diagnosed post mortem.

Does the atrioventricular node conduct? [PDF]
Heart, 1989 It is difficult to be certain wh en the term "conduction" was first applied to the transfer of atrial activation to the ventricles .' In 1894, Engelmann used the word "Leitung", which can be translated as "connection" or as "conduction" .2 In 1906, Tawara described the atrioventricular node, which he termed "Das Reizleitungssystem des Herzens ".'

Models of the cardiac L‐type calcium current: A quantitative review
WIREs Mechanisms of Disease, Volume 15, Issue 1, January/February 2023., 2023 We discuss 73 published models of mammalian ICaL and find differences in gating kinetics, electrochemical driving force, and sensitivity to internal calcium concentrations, leading to considerable variability in their predictions. Abstract The L‐type calcium current (ICaL) plays a critical role in cardiac electrophysiology, and models of ICaL are vital

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