Шаблон:Infobox artery The atrioventricular nodal branch is a coronary artery that supplies arterial blood to the atrioventricular node, which is responsible for initiating muscular contraction of the ventricles. The AV nodal branch is most often a branch of the right coronary artery.

Structure

Origin

The atrioventricular nodal branch sees significant variation in origin:

The right coronary artery supplies the atrioventricular node in around 90% of people.[1][2]

In approximately 2% of people, the vascular supply to the atrioventricular node arises from both the right coronary artery and the left circumflex branch.[3]

Function

The atrioventricular nodal branch supplies the atrioventricular node, allowing for excitation of the ventricles.[1]
