ECG changes in acute pericarditis
ECG changes in acute pericarditis are:
- ST elevation with concavity upward
- T inversion occurs after some days (once ST segment returns to baseline)
- No change in QRS complexes (decrease in QRS voltage may occur in massive pericardial effusions)
- PR segment depression (due to atrial involvement)
- Atrial premature beats, atrial fibrillation
