ST-segment changes: some subtle, some obvious
D. Luke Glancy, MD, and Brian P. Jones, MD
Since the article has no abstract, the first paragraph is shown.
A 52-year-old man came to the emergency department at 3:00 AM with constant retrosternal pain that had awakened him at 1:47 AM and was accompanied by nausea. A standard 12-lead electrocardiogram showed 1 mm of ST-segment elevation in lead III with slightly less elevation in lead aVF and <0.5 mm elevation in lead II (Figure 1). The reciprocal ST-segment depression noted in leads I and aVL confirmed that the minor ST-segment elevation in leads II, III, and aVF represented inferior acute myocardial injury (1).
