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.

Vagally induced hyperpolarization in atrioventricular node
American Journal of Physiology-Heart and Circulatory Physiology, 1986The 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.

Pacing and Clinical Electrophysiology, 1993
The anatomical substrate for atrioventricular (AV) node reentry is unclear. To gain insights into the mechanism of cure of AV node reentry by nonpharmacological techniques, we compared AV node properties in 53 patients undergoing operative therapy (perinodal dissection) and 43 undergoing radiofrequency ablation (28 posterior approach, 15 anterior ...

Effect of Dual Atrioventricular Node Pathways on Atrioventricular Reentrant Tachycardia
Circulation, 1995Background 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

Connexins in the Sinoatrial and Atrioventricular Nodes
2006The 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).
