Remember: Heart attacks occur in paced rhythm’s!
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 diagnosing myocardial infarction.
