Transient complete heart block following catheter ablation of a left lateral accessory pathway. [PDF]
, 2019 A 16-year-old female with symptomatic Wolff-Parkinson-White (WPW) syndrome underwent catheter ablation of a left-sided lateral accessory pathway. The accessory pathway was eliminated with the first ablation lesion; however, the patient immediately ...

Rate-dependency of action potential duration and refractoriness in isolated myocytes from the rabbit AV node and atrium [PDF]
, 2000 During atrial fibrillation, ventricular rate is determined by atrioventricular nodal (AVN) conduction, which in part is dependent upon the refractoriness of single AVN cells.

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 ...

Atrioventricular Reciprocating Tachycardia Mediated by Twin Atrioventricular Nodes
JACC: Clinical Electrophysiology, 2016 A 21-year-old man with univentricular and uniatrial heart came for a third attempt at ablation of recurrent supraventricular tachycardia. He had undergone a previous cardiac surgery of a Blalock–Taussig shunt, and bidirectional Glenn, and the electrophysiological study revealed an ...

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 ...

Cystic tumour of the atrioventricular node [PDF]
Heart, 2003 A 45 year old asymptomatic woman was referred to our clinic because of first degree atrioventricular block on ECG. Transthoracic echocardiography revealed a well delineated mass (27 mm × 29 mm) without …

PLoS ONE, 2014 The aim of the study was to develop a three-dimensional (3D) anatomically-detailed model of the rabbit right atrium containing the sinoatrial and atrioventricular nodes to study the electrophysiology of the nodes. A model was generated based on 3D images
