title: Novel patterns of ischemia and STEMI equivalents.
abstract: Diagnosis of ST-segment elevation myocardial infarction has long been considered time sensitive. Several other electrocardiogram abnormalities, sometimes referred to as "STEMI-equivalents", should also alert the clinician to conditions similarly requiring aggressive intervention. The de Winter/ST/T complex, ST-segment elevation in lead aVR, Wellens' phenomenon, posterior wall myocardial infarction, and pathologic ST changes in the presence of left bundle branch block and pacemakers are all discussed in this article.
