ST-segment elevation in conditions other than acute myocardial infarction.

Early reperfusion therapy has proved beneficial in such infarctions. 2-4 The earlier the reperfusion, the greater the benefit, and the time to treatment is now considered to indicate the quality of care. These days, when thrombolytic treatment and percutaneous intervention are carried out so readily, it is important to remember that acute infarction is not the only cause of ST-segment elevation. The purpose of this review is to describe other conditions that mimic infarction and emphasize the electrocardiographic clues that can be used to differentiate them from true infarction.
