Electrocardiogram Findings in Pericarditis
Pericarditis (inflammation of the sac around the heart) is associated with several ECG findings:
1. Low voltage (i.e., “small”) QRS complexes.
2. Electrical alternans.
3. ST segment elevations with a “concave up” morphology more common.
4. Depression of the PR wave.
5. T wave inversion, but usually only after the ST segment has normalized
