Several stages of pericarditis

Pericarditis is an inflammation of the pericardium. This can lead to ST elevation in all leads. Therefore, it is important to distinguish pericarditis from a myocardial infarction, which has more acute complaints and ST-elevations are limited to the infarct area.

In pericarditis four stages can be distinguished on the ECG:

  • stage I: ST elevation in all leads. PTa depression (depression between the end of the P-wave and the beginning of the QRS- complex)
  • stage II: pseudonormalisation (transition)
  • stage III: inverted T-waves
  • stage IV: normalisation

Keep into account that in stage I pericarditis, ST-elevation is present in all leads except in aVR, V1 and III.
