ECG of the week 14th December 2022 – Interpretation

This ECG was included as a reminder of the Sgarbossa criteria when evaluating patients with a left bundle branch block and coexisting concerns over myocardial ischaemia. The Smith-modified Sgarbossa rules are summarised below:

  1. Concordant ST elevation ≥ 1 mm in ≥ 1 lead
  2. Concordant ST depression ≥ 1 mm in ≥ 1 lead of V1-V3
  3. Proportionally excessive discordant STE in ≥ 1 lead anywhere with ≥ 1 mm STE, as defined by ≥ 25% of the depth of the preceding S-wave
