A
- Anterior and septum of the heart
- ST elevation : V1-V4
3
Q
Left main stem
A
gives rise to both LAD and LCX arteries
* supplying a significant portion of myocardium including anterior, lateral and septal regions.
widespread ST-segment elevation across multiple leads (I, aVL and V1-V6
4
Q
Left circumflex artery (LCX)
A
supplies blood to the lateral wall of the heart.
ST segment elevation in leads I, aVL or V5-V6
5
Q

A
ST elevation in leads II, III and aVF on an ECG indicates an inferior wall myocardial infarction
