Molecular mapping of the rabbit atrioventricular node
The atrioventricular node (AVN) of the heart is responsible for the important conduction delay between atrial systole and ventricular systole. The anatomical architecture and functional properties of the AVN are complex. Ionic currents have been characterised in the AVN at both the whole tissue …

The sophisticated architecture of the rat atrioventricular node
… spontaneously generated in the sinoatrial (SA) node propagates through the atria to reach the atrioventricular (AV) node. As the only conduction pathway between the atria and ventricles, the AV node functions to delay and regulate action potential conduction between the atria and ventricles. …

The electrophysiology of the atrioventricular node in normal and failing rabbit hearts
… investigators have observed abnormal delay in atrioventricular (AV) conduction in a rabbit model of left ventricular dysfunction (LVD) due to apical myocardial infarction. In this model, AV conduction time increased with increasing pacing rates, suggesting the most likely site of delay is the …

Exploration of Supraventricular Conduction with respect to Atrial Fibrillation. Methodological Aspects on Selected Techniques
… non-invasively assess the characteristics of the atrioventricular node during atrial fibrillation. An RR interval distribution with two distinct peaks was seen in most recordings, believed to represent the dual pathway physiology of the atrioventricular node. Atrial activation patterns were …

Spatially-resolved multiomic profiling of the human heart in adulthood and development
… niches, exploring the foetal sinoatrial node niche and its innervation. We leverage the temporal dimension of our dataset to characterise the maturing cardiomyocyte subsets and the gene regulatory networks that underlie these processes. We leveraged somatic mutations called in both RNA- …

Chronische Modulation des parasympathischen Nerventonus des Atrioventrikularknotens : Entwicklung eines Neurostimulators mit transvenöser Sondenimplantation zur ventrikulären Frequenzkontrolle bei Vorhofflimmern
… plexus (IAGP) selectively innervates the AV node. Temporary electrical stimulation of this plexus elicits a reduction of ventricular heart rate in patients with atrial fibrillation.METHODS: In 10 mongrel dogs, the small endocardial area in the right atrium overlying the IAGP was identified by …
