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.

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 ...

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 …

Using Three-Dimensional Lorenz Scatter Plots to Detect Patients with Atrioventricular Node Double Path Caused by Interpolated Ventricular Premature Systoles: A Case Study

Cardiovascular Innovations and Applications, 2021
A series of related electrophysiology phenomena can be caused by the occurrence of interpolated ventricular premature contraction. In our recent three-dimensional Lorenz R-R scatter plot research, we found that atrioventricular ...

Ultrastructure of the mesothelioma of the atrioventricular node [PDF]

Cancer, 1977
In order to determine the histogenesis of tumors of the atrioventricular node, so-called conduction tumors, two such tumors were serially blocked for electron microscopy. Ultrastructurally these tumors were composed of nests of cells arranged in small channels and tubules set in a connective tissue stroma. The cells lining the tubules were flattened or

Sudden cardiac death and thymic hyperplasia in adults: myth or reality? A case report

Egyptian Journal of Forensic Sciences, 2023
Background Sudden cardiac death is a major public health concern. The incidence of sudden cardiac death in young adults remains unclear and is generally underestimated.

Three-dimensional computer model of the right atrium including the sinoatrial and atrioventricular nodes predicts classical nodal behaviours.

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

At the Atrioventricular Crossroads: Dual Pathway Electrophysiology in the Atrioventricular Node and its Underlying Heterogeneities.

Arrhythmia & Electrophysiology Review, 2017
The atrioventricular node (AVN) is a complex structure that performs a variety of functions in the heart. The AVN is primarily an electrical gatekeeper between the atria and ventricles and introduces a delay between atrial and ventricular excitation ...

Late recovery of sinus rhythm following perioperative complete atrioventricular block in a child with congenitally corrected transposition

Annals of Pediatric Cardiology, 2018
We report a patient with l-transposition of the great arteries who developed perioperative complete atrioventricular block at 5 years of age in conjunction with a modified double-switch operation, but had unexpected late recovery of normal sinus rhythm ...
