Arterial vascularisation of the atrioventricular node

Surgical and Radiologic Anatomy, 2000
The aim of this study was to define the anatomic characteristics of the principal arterial source of the atrioventricular node, known as the artery of the atrioventricular node. Forty hearts were studied by various anatomic and radiologic methods: dissection, injection-dissection, injection-corrosion and injection-radiography, but only 23 results were ...

Vagally induced hyperpolarization in atrioventricular node

open access: yesAmerican Journal of Physiology-Heart and Circulatory Physiology, 1986
The effects of postganglionic vagal stimulation on atrioventricular nodal conduction were studied in 12 rabbit atrial-atrioventricular nodal preparations. Vagal stimulation was introduced in the sinus and atrioventricular nodes, separately or in combination, using single bursts of subthreshold stimuli.

Effect of Dual Atrioventricular Node Pathways on Atrioventricular Reentrant Tachycardia

Circulation, 1995
Background Dual atrioventricular (AV) node pathway physiology is frequently observed in patients with AV accessory pathways. Methods and Results To examine the implications of this, we identified 36 patients (19 men and 17 women; mean±SD age, 30±13 years) with both phenomena. The 36

Complete Atrioventricular Block Associated with Lymphocytic Myocarditis of the Atrioventricular Node in Two Young Adult Dogs

open access: yesJournal of Comparative Pathology, 2007
A histological investigation of the atrioventricular (AV) conduction system was performed in two young adult dogs with complete AV block. In both cases, infiltration of lymphocytes and plasma cells into the AV node and loss and disappearance of the ...

Mesothelioma of the Atrioventricular Node

Chest, 1973
In a 17-year-old girl with first degree heart block and two ventricular septal defects, a mesothelioma of the atrioventricular node was noted upon histologic examination of the conduction system. Predominant in the female sex, the condition may occur at any age, 16 of the reported cases being under 30 years of age.

ANATOMY OF THE ATRIOVENTRICULAR NODE AND ATRIOVENTRICULAR CONDUCTION SYSTEM

International Journal of Bifurcation and Chaos, 2003
The anatomy of the atrioventricular conduction system was first described nearly a hundred years ago. Since then, it has been an occasional subject of controversy mainly through a lack of adherence to the original definitions based on histology. The gross landmarks for locating the atrial component of the conduction system are found in the right ...
