| [[w: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.
