It forms the thoracic aorta and ab- dominal aorta. diastole atrial depolarization beginning of ventricular depolarization II, III, aVF RCA occlusion V3, V4 LAD occlusion V1, V2 LAD occlusion I, aVL, V5,V6 Circumflex occlusion ventricular repolarization norepinephrine ( causes pupil dilation, increased sweating, increased heart rate, and increased blood pressure) acetylcholine (decreases heart rate, de- creases blood pressure, pupils constrict, increases digestion and urinary output) RCA supplies Right atrium, right ventricle, SA/AV nodes, posterior portion of right bundle branch
