The electrocardiogram (ECG) is a useful diagnostic tool that allows clinicians to rapidly evaluate patients for acute coronary syndrome. The EKG is crucial in the evaluation of chest pain and diagnosis of ischemia. It is critical for clinicians to be able to accurately recognize these ischemic patterns to allow timely and appropriate cardiovascular care. The classic ST-segment elevation myocardial infarction (STEMI) with rapid reperfusion within less than 60 minutes of acute coronary occlusion improve morbidity and decrees mortality. According to the Fourth Universal Definition of Myocardial Infarction, the STEMI criteria consist of (1) 1 mm ST-segment elevation in any 2 consecutive leads at the J point, excluding V2 and V3; and (2) age- and sex-specific ST-segment elevation thresholds in V2 and V3 (1.5 mm elevation in women regardless of age, 2.5 mm in men <40 years, and 2mminmen aged 40 years), in the absence of left ventricular hypertrophy and bundle branch block (1), but despite that approximately half of high-risk patients with occlusion myocardial infarction fail to meet STEMI criteria, resulting in delays in urgent revascularization (2,3). Definition of occlusion myocardial infarction representing near or total occlusion of a culprit epicardial coronary artery with insufficient collateral circulation causing active infarction, thus necessitating emergency reperfusion (4) In this review we detail the high-risk ECG occlusion myocardial infarction patterns indicative of acute myocardial ischemia resulting from active totally or near totally occlusion of coronary artery
