The atrioventricular node (AV Node) is a bundle of conduction cells that regulate the communication of atrial electrical activity with ventricular electrical activity. The AV node has a long ...

A first-degree atrioventricular node block occurs when conduction through the AV node is slowed, thereby delaying the time it takes for the action potential to travel from the sinoatrial node ...

The atrioventricular node (AVN) has mystified generations of ... providing further insight into basic mechanisms involved in AV conduction. Additionally, procurement of explanted human hearts ...

The impulse is then passed to another node within the heart – the atrioventricular node (AVN). This node is in the lower part of the right atrium.

In this report, 75% (43 of 57 patients) of patients with AV block caused by drugs had blocks at the level of the AV node ... with irregular wide QRS AV = atrioventricular.
