Podcast 846: Early Repolarization vs. Anterior STEMI

Podcast 846: Early Repolarization vs. Anterior STEMI

Contributor: Travis Barlock, MD

Educational Pearls:

  • Early repolarization a benign EKG pattern that can mimic an anterior STEMI
  • Can be seen in the anterior leads typically in young male patients
  • Can differentiate Early Repolarization vs Anterior STEMI by looking at four variables:
    • Corrected QT interval
    • QRS amplitude in V2
    • R wave amplitude in V4
    • ST elevation 60 ms after J point in V3
  • These four variables can be plugged into a formula (available on MDCalc)
  • Note that a longer QT is more corelated with STEMI
