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

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 ...

Multiple anterograde atrioventricular node pathways in patients with atrioventricular node reentrant tachycardia

Journal of the American College of Cardiology, 1996
This study sought to investigate electrophysiologic characteristics and possible anatomic sites of multiple anterograde slow atrioventricular (AV) node pathways and to compare these findings with those in dual anterograde AV node pathways.Although multiple anterograde AV node pathways have been demonstrated by the presence of multiple discontinuities ...

Prolonged PR interval, first-degree heart block and adverse cardiovascular outcomes: a systematic review and meta-analysis [PDF]

, 2016
Objective: First-degree atrioventricular block is frequently encountered in clinical practice and is generally considered a benign process. However, there is emerging evidence that prolonged PR interval may be associated with adverse outcomes. This study

Atrioventricular Node Slow‐Pathway Ablation Reduces Atrial Fibrillation Inducibility: A Neuronal Mechanism

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundRadiofrequency ablation (RFA) for atrioventricular nodal reentrant tachycardia appears to reduce atrial tachycardia, which might relate to parasympathetic denervation at cardiac ganglionated plexuses.

Pathophysiology of Cav1.3 L-type calcium channels in the heart

Frontiers in Physiology, 2023
Ca2+ plays a crucial role in excitation-contraction coupling in cardiac myocytes. Dysfunctional Ca2+ regulation alters the force of contraction and causes cardiac arrhythmias. Ca2+ entry into cardiomyocytes is mediated mainly through L-type Ca2+ channels,

A case of mesothelioma of the atrioventricular node [PDF]

Chinese Journal of Cancer Research, 1997
The case, a 8-year-old boy, who died from traffic accident. Grossly, the heart weights 115g and the inferior part of atrial septum is 3.6-4.0mm in thickness (1.8-2.0mm in thickness of this part in a normal heart). No other abnormalities were found in this heart.
