12 lead ECG Interpretation
Sinus rhythm, inferior wall myocardial infarction
Discussion
Classic inferior wall changes are present in leads II, III, and aVF. STE of greater than or equal to 1mm is consistent with the field impression of ST elevation myocardial infarction. In addition, there's some ST segment depression (reciprocal change) in lead aVL.
Lead V3 also reveals a concerning finding: upsloging ST segment depression. This subtle, but important finding, usually indicates acute occlusion of the proximal LAD. The upsloping ST segments usually appear with tall and upright T waves in the anterior precordial leads.
