Sgarbossa's criteria

Revision as of 02:19, 23 August 2011 by Jswartz (talk | contribs)


  • 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
    • Still consider PCI/t-PA for pts w/ LBBB and "good story" despite not meeting the 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
  • See Media:Sgarbossa.jpg for example of all 3 criteria


  • ≥3 points = 98% probability of STEMI
