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 ...

Medically reviewed by Jeffrey S. Lander, MD Atrioventricular nodal reentrant tachycardia (AVNRT) is a rapid, irregular ...

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

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 ...

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.

Type I second-degree atrioventricular (AV) block should be defined as the ... degree AV block with a narrow QRS complex is almost invariably localised in the AV node. One should remember that what ...

The SA node generates an electrical impulse that causes the upper heart chambers (atria) to contract. The signal then passes through the atrioventricular (AV) node to the lower heart chambers ...

Healthcare professionals may also call this condition first-degree atrioventricular (AV ... a group of cells in between them, called the AV node. It is what makes the heart beat and push blood ...

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.

The University of Manchester-led study found that long-term exercise in retired racehorses – the best available model of the athlete’s heart - and in mice, triggered molecular changes in a part of the ...
