Acute anterior STEMI. What may appear to be wide QRS complexes in leads V2 to V6 are actually marked ST elevations, with hyperacute T waves, due to acute transmural anterior ischemia with myocardial infarction. The inferior leads show reciprocal ST depressions. Q waves are starting to appear in the precordial leads. This ST-T pattern, sometimes called "tombstones" in clinical parlance, is more technically known as a "monophasic current of injury." Coronary angiography showed a proximal occlusion of the left anterior descending coronary artery, treated with a percutaneous coronary intervention.
