ST. segment elevation: is it a possible infarct?
In patients with acute substernal pain seen at Emergency Departments, ST segment elevations are considered the hallmark of an acute myocardial infarct. Acute substernal pain associated with ST segment elevations is the inclusion criteria for thrombolytic therapy. However, there are other conditions, which may present with ST segment elevation in which thrombolytic therapy is not indicated. Acute pericarditis and ECG variants of normal must also be considered in the differential diagnosis. Three cases are presented that illustrate this ECG presentation. It is of paramount importance, that the Emergency Department physician who does the triage for these patients be able to identify the various causes of ST segment elevation.
