Diagnosis of ST elevation in the absence of left ventricular hypertrophy and associated left bundle branch block were agreed by the ESC, ACCF, AHA and World Heart Federation, and were considered as global consensus in diagnosis of acute MI. ST elevation can be summarized as follows: ST elevation: ST elevation ≥ 2 mm in men or 1.5 mm in women on V2 V3 leads and / or ≥ 1 mm in other chest leads and limb leads.
