ECG: Nonspecific ST-T changes may be observed in persons with myopericarditis. Severe disease may cause Q waves, ventricular tachyarrhythmias, and heart block. ECG findings may demonstrate evolution through several stages of myopericarditis, as follows:

  • Stage I - Diffuse ST elevation with PR depression

  • Stage II - Normalization of ST and PR segments

  • Stage III - Deep symmetric inversion of T waves

  • Stage IV - May revert to normal or permanent T-wave inversions
