Stage II: ST segment elevation and PR depression have resolved and ... and thus the ECG is back to normal. Note: The ECG changes with pericarditis must be distinguished from those of early ...

Electrocardiographic changes are common and typically evolve through four stages: Stage I: diffuse ST-segment elevation (typically concave up) and PR-segment depression are recorded in the first ...

The PR segment is the portion of the ECG from the end of the P ... certain cardiac disease states. PR segment depression can be a signal for pericarditis or atrial infarction.

The clinical diagnosis of acute pericarditis is based on simple criteria: typical chest pain, pericardial friction rub (Figure 2), widespread ST-segment elevation (Figure 3) and pericardial ...
