Sgarbossa - isn't that a caribbean cardiologist cocktail?

Dr. Smith urges us to know the Sgarbossa Criteria and advocate for our patients.  Start with his blog post here:

Remember:​
The original criteria used to diagnose MI in patients with LBBB are:

• Concordant ST elevation > 1mm in leads with a positive QRS complex (score 5)
• Concordant ST depression > 1 mm in V1-V3 (score 3)
• Excessively discordant ST elevation > 5 mm in leads with a negative QRS complex (score 2).

A total score of  ≥ 3 has a specificity of 90% for MI.

Also check out the modified Sgarbossa Criteria from Dr. Smith's blog

• ≥ 1 lead with ≥1 mm of concordant ST elevation
• ≥ 1 lead of V1-V3 with ≥ 1 mm of concordant ST depression
• ≥ 1 lead anywhere with ≥ 1 mm STE and proportionally excessive discordant STE, as defined by ≥ 25% of the depth of the preceding S-wave.
