The ECG technician brings the ECG and alerts that the automated reading is for an anterior ST elevation myocardial infarction. The ECG demonstrates the findings of early repolarization with J point elevation and ST segment elevation in leads I, II, AVF, and V2–V6. Early repolarization can be confused with acute myocardial infarction or pericarditis. Several criteria can be used to identify patients with early repolarization although none are 100% accurate. These include absence of chest pain, young age, widespread ST elevation, marked J-point elevation, concavity of initial upsloping portion of ST segment, notching or irregular contour of J point, and current ECG is unchanged from prior ECGs. In early repolarization the ST segments remain constant whereas, in general, the ECG in patients with acute pericarditis evolves over time.Read More
