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 ...

Mobitz type I, also known as the Wenckebach block, is a subtype of second-degree atrioventricular (AV) block. Mobitz type I is a type of conduction disorder, which happens when the electrical signals ...

Third-degree atrioventricular nodal block, also known as third-degree heart block or complete heart block, occurs when no action potentials conduct through the AV node. This results in the P waves ...

What Is the Heart Conduction System? The heart conduction system is made up of cells, nodes, and signals that help your heart to beat. In fact, the cardiac conduction system is responsible for our ...

The right coronary artery and the atrioventricular node are adjacent to the annulus and are important anatomical considerations for surgical or transcatheter interventions. The right coronary artery ...
