From: Electrocardiographic patterns predict the presence of collateral circulation and in-hospital mortality in acute total left main occlusion

Fig. 2

A–C Illustrate STE in both leads aVR and aVL in a patient with total ULM occlusion and collateral filling of LAD (red arrow). D–F illustrate STE in the precordial and lateral extremity leads in a patient with total ULM occlusion and no collateral circulation. G–I illustrate STE in lead aVR in a patient with total ULM occlusion and collateral filling of the LAD (red arrow), diagonal branch (yellow arrow), and LCX (blue arrow). J–L illustrate STE in leads avR and V1 in a patient with subtotal ULM obstruction and no collateral circulation. ULM, unprotected left main occlusion; STE, ST-segment elevation; LAD, left anterior descending coronary artery; LCX, left circumflex artery
