ST Elevation | Location | Coronary Artery | Complications |
V1-V2 | Septal | Septal branch | Left ventricular dysfunction:
-Decreased CO2 -CHF, LBBB, RBBB -Left PFB -Infranodal block (2 ̊or 3 ̊) |
V2-V4 | Anterior | LAD | |
I, aVL, V5, V6 | Lateral | Circumflex | Left ventricular dysfunction:
-Decreased CO2 -CHF, Infranodal block (2 ̊or 3 ̊) |
II, III, aVF | Inferior | RCA | -Hypotension (NTG/morphine)
-A-fib/flutter -PACs Infranodal block (2 ̊and 3 ̊) -Papillary muscle rupture (murmur) |
