Mesothelioma of the Atrioventricular Node
Chest, 1973In 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.

Electrical activity in sinus node and atrioventricular node
American Heart Journal, 1956Summary 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, 2003The 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 ...

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!

Atrioventricular Node Ablation
Heart Failure Clinics, 2015Cardiac resynchronization therapy (CRT) is a device-based, nonpharmacologic approach that has shown to improve the outcome in patients with heart failure in terms of mortality and morbidity reduction. Large randomized trials have virtually enrolled patients in New York Heart Association class III-IV, with reduced left ventricular ejection fraction ...

Mapping the Atrioventricular Node
New England Journal of Medicine, 2007A 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, 2000The 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 ...

Mesothelioma (Coelothelioma) of the Atrioventricular Node
Chest, 1971This 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, 1967AbstractThe 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.
