Sgarbossa's Criteria
Sgarbossa's Criteria (pronunciation: sgar-bos-sa's cri-te-ria) is a set of electrocardiogram (ECG) findings used to identify myocardial infarction (MI) in the presence of a left bundle branch block (LBBB) or a ventricular paced rhythm.
Etymology
The criteria are named after Dr. Elena B. Sgarbossa, a cardiologist who first described them in 1996.
Criteria
The criteria consist of three main points:
- Concordant ST elevation > 1mm in leads with positive QRS complex (5 points)
- Concordant ST depression > 1mm in V1-V3 (3 points)
- Excessively discordant ST elevation > 5mm in leads with negative QRS complex (2 points)
A score of ≥3 is considered positive for myocardial infarction.
