Original Sgarbossa Criteria (STEMI in LBBB): 0 — Original Sgarbossa criteria total. Interpretation: Original Sgarbossa criteria total What to do: Neutral numeric output only; no authorized clinical risk band is assigned. Interpret in the cited source population and clinical context. Inputs: Concordant ST elevation ≥1 mm (same direction as QRS): false; ST depression ≥1 mm in leads V1–V3: false; ST elevation ≥5 mm with discordant pattern: false Source: Sgarbossa EB et al.
