Atrioventricular node information

The atrioventricular node or AV node electrically connects the heart's atria and ventricles to coordinate beating in the top of the heart; it is part of...

signal travels from the SA node to the ventricles through the atrioventricular node (AV node). In an AV block, this electrical signal is either delayed or...

classifications involve the broad categories of sinus node dysfunction (SND), atrioventricular block, and other conduction tissue diseases. However, bradycardia...

system of the heart, it transmits the electrical impulses from the atrioventricular node (located between the atria and the ventricles) to the point of the...

The atrioventricular nodal branch is a coronary artery that supplies arterial blood to the atrioventricular node, which is responsible for initiating muscular...
