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 ...

The atrioventricular node (AVN) has mystified generations of investigators over the last century and continues today to be at the epicenter of debates among anatomists, experimentalists ...

AV node ablation can be utilized. Remember that all atrial action potentials must pass through the AV node to reach the ventricle. AV node ablation destroys this connection stopping any atrial ...

The atrioventricular, or AV, node is the second key area of the heart’s electrical wiring. The atrioventricular node takes information about how fast the heart is beating from the sinoatrial ...

There is increasing evidence that cardiac resynchronization therapy devices may be beneficial in selected populations after atrioventricular node ablation. The limitations of this approach include ...

Medically reviewed by Richard N. Fogoros, MD The right atrium is one of the heart's upper chambers that plays a role in blood ...

When Raigan Miller was 11 years old, her heart began acting strangely after she was hit in the chest with a kickball during gym class. The 12-year-old’s parents, Andy and Sara Miller of ...

The presence of type I second-degree AV block with a narrow QRS complex is almost invariably localised in the AV node. One should remember that what appears to be narrow QRS type II block may be a ...

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.
