Its blood supply is by way of the av node artery, a branch of the right coronary artery (rca) that arises usually at the crux cordis, the point of division of the rca into the posterior. Results we found that the right superior descending artery supplied blood to the atrioventricular node in 14 of ery supplied blood to the 8 of the 20 hearts (40%). A more comprehensive understanding of ccs arterial anatomy is essential for advancing electrophysiological studies.

Posteriorly, via the crista terminalis, and anteriorly, via the interatrial septum. The av bundle, or his bundle, emerges from the compact av node and. When the region enclosed by the white circle in a is magnified in b, the thin atrioventricular node artery (b, arrow) can be observed, ascending within the inferior pyramidal.
Understanding this blood supply is crucial for cardiologists and.
The av node receives two inputs from the atria: The atrioventricular node receives its arterial blood supply from the atrioventricular nodal artery, which is a large arterial branch in the interventricular septum, arising from the right coronary. The primary blood vessel supplying the av node is the right coronary artery (rca), specifically its posterior interventricular branch. The blood supply of the av node is via the av nodal artery.
