Overview

Acute pericarditis can mimic myocardial infarction (STEMI) signs and electrocardiogram and present with chest pain and cardiac enzyme (bio-marker) elevation the differentiation is made by specific features.

Electrocardiogram

  • Acute pericarditis can mimic myocardial infarction (STEMI) signs and electrocardiogram and present with chest pain and cardiac enzyme (bio-marker) elevation.[1]
  • IF pericarditis does not follow myocarditis and vice versa, the differentiation is made as following:[2][3][4]
    • Morphology:
      • Start of ST-elevation: in acute pericarditis begins at the J point(termination of depolarization junction)
      • STEMI patients present a dome-shaped ST-elevation that can be more than 5MM in height.
    • Distribution:
      • Pericarditis shows a non-specific ST-elevation pattern while STEMI shows specific changes based on the infarction location.
    • Reciprocal changes:
      • STEMI is often associated with reciprocal changes.
      • Pericarditis reciprocal changes are just seen in leads aVR and V1.
    • Concurrent ST and T wave changes:
    • PR segment:
      • Pericarditis shows PR elevation in aVR with PR depression in other leads because of atrial injury.
      • STEMI does not show such changes.
    • Other signs:
      • Hyperacute T waves
      • New pathologic Q waves
      • QT prolongation
      • These signs are rarely seen in acute pericarditis
  • Shown below is an EKG with the presence of micro-voltage and electrical alternans suggesting pericardial effusion and cardiac tamponade.
