WebThe best ECG variables for the diagnosis of acute myocardial infarction were ST elevation ⩾0.1 mV in ⩾1 lateral or inferior lead or ST elevation ⩾0.2 mV in ⩾1 anteroseptal precordial lead. These criteria correctly classified 83% of subjects with a sensitivity of 56% and a specificity of 94%. WebTo be diagnostic, ST segment elevation must be at least one small square above the baseline and observed in two or more contiguous leads in order to localize the ischemic injury. For example, ST elevation in leads II, III and aVF shows inferior wall ischemia, and ST elevation in leads V 5 and V 6 shows left ventricular anterolateral ischemia.
