Background
- Assesses likelihood that pt w/ chest pain and baseline LBBB has myocardial damage (+CK-MB)
- Criteria do NOT need to be found in contiguous leads
- RBBB should NEVER have ST elevation
- Low Sn, High Sp
Criteria
- 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
Points
- ≥3 points = 98% probability of STEMI
