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.
| Points |
Probability STEMI |
| 0 | 16% |
| 5-10 | 88-100% |
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
