- ≥3 points = 98% probability of STEMI
- ST elevation ≥1 mm in a lead with upward (concordant) QRS complex - 5 points
- ST depression ≥1 mm in lead V1, V2, or V3 - 3 points
- ST elevation ≥5 mm in a lead with downward (discordant) QRS complex - 2 points
Smith's modification
- Changes the 3rd rule of original Sgarbossa's Criteria to be ST depression OR elevation discordant w/ the QRS complex and w/ a magnitude of at least 25% of the QRS increases Sn from 52% to 91% at the expense of reducing Sp from 98% to 90%[1]
