| Artery: Atrioventricular nodal branch | |
|---|---|
| Sternocostal surface of heart. | |
| ARTERIES: RCA = right coronary AB = atrial branches SANB = sinuatrial nodal RMA = right marginal LCA = left coronary CB = circumflex branch LAD/AIB = anterior interventricular LMA = left marginal PIA/PDA = posterior descending AVN = atrioventricular nodal VEINS: SCV = small cardiac ACV = anterior cardiac AIV/GCV = great cardiac MCV = middle cardiac CS = coronary sinus |

| Latin | ramus nodi atrioventricularis |
The atrioventricular nodal branch most frequently arises as a distal branch from the right coronary artery, but occasionally the atrioventricular node receives blood from the circumflex branch of left coronary artery.
