Sgarbossa Criteria ,[object Object],[object Object]

Sgarbossa Criteria Odds Ratio: a measure of the degree of association; for example, the odds of exposure among the cases compared with the odds of exposure among the controls (www.cefpas.it/ebm/tools/glossary.htm) Score 2 points OR 4.3 ST Elevation ≥ 5 mm and discordant with QRS complex Score 3 points OR 6.0 ST Depression ≥ 1 mm in V1, V2, V3 Score 5 points Odds Ratio (OR) 25.2 ST Elevation ≥ 1 mm and concordant with QRS complex
