AbstractThe electrocardiographic (ECG) diagnosis of ST-segment elevation myocardial infarction (STEMI) represents a challenge to all health care providers, particularly so for the novice ECG interpreter. We have developed--and present in this article--a 4-step algorithm that will detect STEMI in most instances in the prehospital and other nonemergency department (ED) settings. The algorithm should be used in adult patients with chest pain or equivalent presentation who are suspected of STEMI. It inquires as to the presence of ST-segment elevation as well as the presence of STEMI confounding/mimicking patterns; the algorithm also makes use of reciprocal ST-segment depression as an adjunct in the ECG diagnosis of STEMI. If STEMI is detected by this algorithm, then management decisions can be made based upon this ECG diagnosis. If STEMI is not detected using this algorithm, then we can only note that STEMI is not "ruled in"; importantly, STEMI is not "ruled out." In fact, more expert interpretation of the ECG will be possible once the patient (and/or the ECG) arrive in the ED where ECG review can be made with the more complex interpretation used by expert physician interpreters.Copyright © 2012 Elsevier Inc.
