A. Left circumflex – Explanation
This is most typical of a left circumflex occlusion although may rarely be seen if the left anterior
descending is affected
ECG: coronary territories
The table below shows the correlation between ECG changes and coronary territories:
| ECG changes | Coronary artery | |
| Anteroseptal | V1-V4 | Left anterior descending |
| Inferior | II, III, aVF | Right coronary |
| Anterolateral | V4-6, I, aVL | Left anterior descending or left circumflex |
| Lateral | I, aVL +/- V5-6 | Left circumflex |
| Posterior | Tall R waves V1-2 | Usually left circumflex, also right coronary |
