The right coronary aery supplies all of the following pas of the conducting system in the hea, EXCEPT?
Branches of the right coronary aery supplies the SA node, AV node and AV bundle. Right bundle branch of atrioventricular bundle is supplied by the left coronary aery. Left bundle branch is supplied by right and left coronary aery. The right coronary aery arises from the anterior aoic sinus of the ascending aoa and runs forward between the pulmonary trunk and the right auricle. It descends almost veically in the right atrioventricular groove, and at the inferior border of the hea it continues posteriorly along the atrioventricular groove to anastomose with the left coronary aery in the posterior interventricular groove. Branches of right coronary aery are: Right conus aery, anterior ventricular branches, posterior ventricular branches, posterior interventricular aery and atrial branches.
