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

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).

Atrioventricular Node Ablation

Heart Failure Clinics, 2015
Cardiac 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 ...

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.

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.

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

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

Neurona in the region of the atrioventricular node

Human Pathology, 1981
A three month old infant died of apparent sudden infant death syndrome. Autopsy showed a neuroma in the region of the atrioventricular node, unassociated with neurofibromatosis. The atrioventricular node and bundle of His were normal. It was not possible to ascribe the sudden death to the neuroma.

Selective Hypervagotonia Isolated to the Atrioventricular Node

Pacing and Clinical Electrophysiology, 1988
Thirteen patients with recurrent unexplained syncope or presyncope underwent electrophysiological evaluation. A prolonged effective refractory period and functional refractory period of the atrioventricular node as well as slow paced rate to atrioventricular block were the only abnormalities found. Ventricular tachycardia could not be induced.
