A, Example of definite early repolarization (ER) using Epidemiological Cardiology Research Center (EPICARE) definition. B, Example of probable ER using EPICARE definition. Definite and probable patterns of ER—definite ER is defined as presence of STJ elevation >1 mm in ≥50% of beats, T-wave amplitude ≥5 mm, prominent J point, upward concavity of the ST, and a distinct notch or slur on the downstroke of the R wave in any of V₃ through V₆; or STJ elevation >2 mm in ≥50% of beats, T-wave amplitude ≥5 mm, prominent J point and upward concavity of the ST segment in any of V₃ through V₆. Probable ER is defined a STJ elevation >1 mm in ≥50% of beats, prominent J point, and upward concavity of the ST segment in any of V₃ through V₆ and T-wave amplitude ≥8 mm in any of the chest leads.
