Background

  • Assesses likelihood that pt w/ chest pain and baseline LBBB has myocardial damage (+CK-MB)
    • Criteria also applies to LBBB due to paced rhythm
  • Low Sn, High Sp
    • Still consider PCI/t-PA for pts w/ LBBB and "good story" despite not meeting the criteria

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

Points

  • ≥3 points = 98% probability of STEMI
