ACS anatomical correlation
| Coronary Artery | Location | ECG Leads | Complications |
| LAD | Anteroseptal. | V1-V3 | Left ventricular dysfunction:
-Decreased CO2 -CHF, LBBB, RBBB -Left PFB -Infranodal block (2 ̊or 3 ̊) |
| LAD | Anterior | V2-V4 | |
| LCA | Lateral | I, aVL, V4-6 | Left ventricular dysfunction:
-Decreased CO2 -CHF, Infranodal block (2 ̊or 3 ̊) |
| RCA | Inferior | II, III, aVF | -Hypotension (NTG/morphine) -Supranodal 1 ̊ HB
-A-fib/flutter -PACs Infranodal block (2 ̊and 3 ̊) -Papillary muscle rupture (murmur) |
| CA | Right ventricular | V4R (also II, III, aVF) | |
| RCA (90%), LCA (10%) | Posterior | R waves in V1, V2 (also V7-9) | |
| LCMA | Anterolateral | avR (STE) |
