Smith 2012 unweighted modified Sgarbossa for STEMI equivalent in LBBB
Smith 2012 unweighted modified Sgarbossa for STEMI equivalent in LBBB. Positive if ANY of three caller-assigned flags is true: concordant ST elevation ≥1 mm in a lead with positive QRS, concordant ST depression ≥1 mm in V1–V3, or ≥1 mm discordant STE with ST/S ratio ≤ −0.25 (STE ≥25% of the preceding S-wave). Not the original Sgarbossa 1996 5/3/2 points score. Not a 5 mm discordant rule. magent does not measure the ECG. Not a diagnosis.
