Podcast 628: ST Elevation

Contributor: Peter Bakes, MD

Educational Pearls:

  • STEMI criteria is not just 1mm elevation in contiguous leads
    • 1.5 mm in V2-V3 for women
    • 2.0 mm in V2-V3 for men
    • 2.5 mm in V2-V3 for men under 40
  • Inferior MI typically have ST elevation in leads II, III and aVF
    • Usually inferior MI's show reciprocal changes (ST depression) in the lateral leads.
  • Lateral MI typically elevation in V5, V6, I, and aVL
  • Anterior MI show elevation in leads V1-4
  • Right sided MIs have mixed pattern, showing elevation in V1-V2 and V4 along with the inferior leads.
  • Right sided MI's are very sensitive to nitrates, especially if they become intubated because this combination can drop pre-load significantly leading to profound hypotension
