ST-segment elevation in pulmonary thromboembolism.

In addition to acute myocardial infarction (AMI), there are several causes of ST-segment elevation,1 such as early repolarization, variation of the normal pattern (male pattern), left ventricular hypertrophy, complete left bundle branch block, acute pericarditis, myocarditis, Brugada syndrome, post-cardioversion, hyperkalemia, and pulmonary thromboembolism (PTE). However, the distinction between those conditions and AMI is clinically relevant, because of the benefit provided by early reperfusion in the presence of AMI with STsegment elevation. This case report is about a patient diagnosed with PTE, whose electrocardiogram (ECG) mimicked AMI.
