You are here: Home » Cardiology Notes » Localization of myocardial infarction:
| Infarct location | Leads depicting primary ECG changes | Likely vessel * involved |
| Inferior | II,III,aVF | RCA |
| Septal | V1-V2 | LAD |
| Anterior | V3-V4 | LAD |
| Antero-septal | V1-V4 | LAD |
| Extensive Anterior | I,aVL,V1-V6 | LAD |
| Lateral | I,aVL,V5-V6 | CIRC |
| High Lateral | I, aVL | CIRC |
| Posterior | ** Prominent R in lead V1 | RCA or CIRC |
| Right ventricular | *** ST elevation in lead V1,and more specifically, V4R in the setting of inferior infarction | RCA |
*this is a simple generalization, variations occur.
** Usually in association with inferior or lateral infarctions.
***Usually in association with inferior infarctions.
