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 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%.
