Dual atrioventricular nodes [PDF]

Heart, 2014
To the Editor I read with great interest the ‘challenge’ posed by the electrocardiographic recording in issue 7 of Heart for 2014.1 I also noted with interest that the authors suggest that Monckeberg provided the first account of such dual nodes in 1993. Since Monckeberg was long since dead by that date, this must be some mistake!

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.

Mapping the Atrioventricular Node

New England Journal of Medicine, 2007
A 75-year-old woman presented with dyspnea, an awareness of rapid heart action, and permanent atrial fibrillation with a rapid ventricular response that had been resistant to treatment with beta-blockers, calcium-channel blockers, digoxin, and multiple cardioversions. For severe rheumatic aortic and mitral stenosis, she had undergone replacement of the

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 ...

Connexins in the Sinoatrial and Atrioventricular Nodes

2006
The sinoatrial node (SAN) and the atrioventricular node (AVN) are specialized tissues in the heart: the SAN is specialized for pacemaking (it is the pacemaker of the heart), whereas the AVN is specialized for slow conduction of the action potential (to introduce a delay between atrial and ventricular activation during the cardiac cycle).

Mesothelioma (Coelothelioma) of the Atrioventricular Node

Chest, 1971
This is the 12th reported case of benign mesothelioma of the atrioventricular (AV) node, studied both clinically and pathologically. In this case, serial sections were done throughout the entire conduction system. The patient clinically showed AV block with a nodal pacemaker.

Reconstruction of the human atrioventricular node

The Anatomical Record, 1967
AbstractThe right atrioventricular junction and A‐V node area in each of five human hearts was studied histologically in serial sections. The A‐V node of a 54‐year old female was reconstructed in four colors to provide a three‐dimensional model of cardiac relationships, blood supply, and nodal configuration.

Vagally induced hyperpolarization in atrioventricular node [PDF]

American 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.

Electrical activity in sinus node and atrioventricular node

American Heart Journal, 1956
Summary Complicated multiphasic differential complexes of a low voltage are demonstrated locally in the anatomic sinus nodal region. This local sinus activity is, in differential leads, most characteristic in that part of the sinus node, where, in simultaneous unipolar leads, the initial negativity is found. Pure initial negativity is seen only in a

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 ...
