Atypical Electrocardiographic Presentations in Need of Primary Percutaneous Coronary Intervention

Early initiation of reperfusion therapy remains the cornerstone of successful management for ST-elevation myocardial infarction (STEMI). Rapid restoration of coronary blood flow relies on prompt recognition of the typical ST-segment elevation on a 12-lead electrocardiogram (ECG), - a surrogate for coronary occlusion or critical stenosis - allowing timely activation of the STEMI protocol cascade, with a major positive impact in mortality and clinical outcomes. However, atypical, very high risk ECG patterns - known as “STEMI equivalents” - are present in 10-25% of patients with ongoing myocardial ischemia in need of urgent primary percutaneous coronary intervention.
