ACS anatomical correlation
ST Elevation | Location | Coronary Artery | Complications |
V1-V2 | Septal | Septal branch | Left ventricular dysfunction:
-Decreased CO2 -CHF, LBBB, RBBB -Left PFB 2 ̊or 3 ̊ block |
V2-V4 | Anterior | LAD | |
I, aVL, V5, V6 | Lateral | Circumflex | Left ventricular dysfunction:
-Decreased CO2 -CHF, Infranodal block (2 ̊or 3 ̊) |
I, aVL, V2-6 | Anterolateral | LAD + circumflex = Left main or 2 critical lesions | |
II, III, aVF | Inferior | RCA |
-Hypotension (NTG/morphine) - Second degree type 1 -A-fib/flutter -PACs -Papillary muscle rupture (murmur) |
V1 III > II

Right ventricle | RCA | |
ST Depression in V1, V2; R>S in V1

Posterior | RCA (90%), LCA (10%) | |
avR (STE) | Anterolateral | Left Main |
