Background

-Sgarbossa Criteria help in assessing the likelihood that a patient with chest pain and a baseline LBBB is having a STEMI.

-Low Sens, High Specificity

Sgarbossa Criteria

1. ST-segment elevation ≥1 mm in a lead with upward (concordant) QRS complex (5 points)

2. ST-segment depression ≥1 mm in lead V1, V2, or V3 (3 points)

3. ST-segment elevation ≥5 mm in a lead with downward (discordant) QRS complex (2 points)

Specific, not sensitive.

Notes

-Unlike general AHA STEMI criteria, the Sgarbossa criteria do NOT need to be found in contiguous leads

-Multiple elements, only 3 have been sufficiently validated

-A RBBB should NEVER have ST elevation
