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 ...

Anatomical Ablation of the Atrioventricular Node [PDF]
Arrhythmia & Electrophysiology ReviewBackground: 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.

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 ...

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

Cystic Tumor of the Atrioventricular Node Causing Rapid-Onset and Reversible Complete Heart Block [PDF]
JACC: Case Reports, 2023 Cystic tumors of the atrioventricular node are rare primary cardiac neoplasms, frequently reported as a postmortem diagnosis during autopsy. Despite their small size, they can present with complete heart block or sudden cardiac death.

An atrioventricular node model incorporating autonomic tone [PDF]
Frontiers in Physiology, 2022 The response to atrial fibrillation (AF) treatment is differing widely among patients, and a better understanding of the factors that contribute to these differences is needed. One important factor may be differences in the autonomic nervous system (ANS)

Outcomes of Atrioventricular Node Ablation and Pacing in Patients with Heart Failure and Atrial Fibrillation: From Cardiac Resynchronization Therapy to His Bundle Pacing [PDF]
Journal of Cardiovascular Development and Disease, 2023 Objective: To review the relevant literature on the use of atrioventricular node ablation and pacing in patients with heart failure and atrial fibrillation. Methods: APubMed/MEDLINE and SCOPUS search was performed in order to assess the clinical outcomes

Electrophysiological differences of randomized deep sedation with dexmedetomidine versus propofol [PDF]
BMC AnesthesiologyBackground Dexmedetomidine and propofol are common sedatives in intensive care units and for interventional procedures. Both may compromise sinus node function and atrioventricular conduction.
