The electrical relay station between the upper and lower chambers of the heart. Abbreviated AV node. Electrical signals from the atria must pass through the AV node to reach the ventricles. The AV node, which controls the heart rate, is one of the major elements in the cardiac conduction system. The AV node serves as an electrical relay station, sl [..]

[L. atrium, yard, court, hall + ventriculus, the stomach + nodus, knot] A group of slow-conducting fibers in the atrium of the vertebrate heart that are stimulated by impulses originating in the sinoa [..]

A mass of tissue that can be found inside the right atrium; transmits electrical impulses to certain areas of the heart.

A microscopic aggregation of specialized cardiac fibers located in the interatrial septum of the heart that are a part of the conduction system of the heart; AV node. atrioventricular valve

Also called AV node: cluster of cells between the atria and ventricles that slows the electrical current of the heart as it passes through to the ventricles.

Also known as the AV node. A major part of the electrical system in the heart that acts as a gateway between the atria and the ventricles. An electrical signal generated by the sinoatrial node (the he [..]

A small nodular mass of specialized Muscle fibers located in the interatrial septum near the opening of the Coronary Sinus. It gives rise to the Atrioventricular Bundle of the conduction system of the [..]

(AV node) Specialized muscle cells that branch into a network of Purkinje fibers, which conduct electrical stimulation six times faster than other parts of the heart.

a cluster of cells between the atria and ventricles that regulate the electrical current.

Specialized conducting tissue in the right atrium where the atrial and ventricular electrical systems meet; acts as an electrical road or gate connecting the atria to the ventricles; normally the AV N [..]
