摘要：
Combined anterior and inferior ST elevation due to occlusion of wrapped left anterior descending artery (LAD) is well reported in the literature. However, there is rare literature mentioned about inferolateral ST elevation in this patient group. Herein, we report a case of acute proximal wrapped LAD occlusion with initial electrocardiographic sign of inferolateral ST elevation. The most likely mechanism of this electrocardiographic finding might be related to old anteroseptal myocardial infarction, combination with other coronary abnormality, such as chronic total occlusion of left circumflex artery that caused larger injury current in inferolateral than anteroseptal myocardium, and made anteroseptal leads reveal isoelectric pattern.
