The Anatomy of the Atrioventricular Node. [PDF]

J Cardiovasc Dev Dis
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. Lack of detailed knowledge of the location of the node relative to the atrial and ventricular septal structures has ...

Anatomical Ablation of the Atrioventricular Node. [PDF]

Arrhythm Electrophysiol Rev
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. Ablation of the His bundle may reduce the possibility of a robust junctional escape rhythm. It was hypothesised that specific AV nodal ablation is feasible and safe. Methods:

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 ...

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 ...

Atrioventricular Junction Ablation with High-Definition Recording of Atrioventricular Node Potential. [PDF]

J Cardiovasc Dev Dis
Atrioventricular (AV) node ablation represents an established therapeutic option in the management of atrial fibrillation (AF) and other atrial tachyarrhythmias, particularly in patients with symptomatic tachycardia who remain unresponsive or intolerant ...

Paradoxical heart rate response after atropine sulfate administration in total atrioventricular block complicating acute myocardial infarction: A case report

Bali Journal of Anesthesiology, 2021
Acute myocardial infarction is sometimes complicated by atrioventricular block. Advanced cardiac life support guideline for the treatment of atrioventricular block suggests early use of atropine.

Ivabradine in the treatment of non‐paroxysmal junctional tachycardia with interference atrioventricular dissociation: A case report

Annals of Noninvasive Electrocardiology, 2023
Ivabradine reduces the heart rate by selectively inhibiting the If current of the sinoatrial node, mainly for the treatment of chronic heart failure with decreased left ventricular systolic function and inappropriate sinus tachycardia, but the inhibitory
