Modified Sgarbossa Criteria to aid in diagnosing STEMI in the setting of LBBB

• Can be used in the setting of induced (paced) LBBB
• Unweighted scoring (any of the following indicates STEMI equivilance)
  • Concordant ST elevation
  • Concordant ST depression in V1,V2,V3
  • Inappropriate discordance of >25% ST elevation / S wave amplitudes
• Improves your test metrics from the original criteria from sens/spec of 36%/96% to 80%/99% respectively in a new validation study
