Sgarbossa Criteria: Sensitivity and Specificity
Introduction:
None written. Excerpt from the entry in Acute Coronary Syndrome:
in patients with LBBB, Sgarbossa et al proposed the following ECG criteria for acute MI: ST elevation >= 1mm concordant with QRS
ST depression >= 1mm in V1, V2, or V3
ST elevation >= 5mm discordant with QRS
in patients with LBBB, Sgarbossa et al proposed the following ECG criteria for acute MI:
In the HERO-2 trial, a positive ECG represented either of the first two criteria, with the last one dropped (previously they had used a scoring system).
The numbers above are from HERO-2; note that replication in a community setting gave a sensitivity of only 10% with a specificity of 100%.

37.2% sensitive, 96.6% specific
