Anatomic-electrophysiological correlations concerning the pathways for atrioventricular conduction. [PDF]

open access: yes, 2001
The remarkable success of radiofrequency ablation in recent decades in curing atrioventricular nodal reentrant tachycardias has intensified efforts to provide a solid theoretical basis for understanding the mechanisms of atrioventricular transmission ...

Cystic Tumor of the Atrioventricular Node Causing Rapid-Onset and Reversible Complete Heart Block

open access: yesJACC: 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.

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

open access: yesJournal 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 ...

Atrioventricular Node Ablation to Enhance Resynchronization Therapy Response in a Patient With Complete Atrioventricular Block

open access: yesJACC: Case Reports, 2021
Up to one-third of patients who undergo cardiac resynchronization therapy do not obtain clinical benefit. A systematic approach can identify treatable causes in many nonresponding patients.

Trimethoprim/Sulfamethoxazole-Induced Bradycardia, Renal Failure, AV-Node Blockers, Shock and Hyperkalemia Syndrome

open access: yesClinical Practice and Cases in Emergency Medicine, 2019
BRASH (bradycardia, renal failure, atrioventricular-node blockers, shock, and hyperkalemia) syndrome is a recently coined term for a condition that describes the severe bradycardia and shock associated with hyperkalemia in patients on atrioventricular ...

Transient complete heart block following catheter ablation of a left lateral accessory pathway. [PDF]

open access: yes, 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 ...

Ultrastructure of the Human Atrioventricular Node [PDF]

open access: yesCirculation, 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 ...

Rate-dependency of action potential duration and refractoriness in isolated myocytes from the rabbit AV node and atrium [PDF]

open access: yes, 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.
