Figure 031_7505. Classic electrocardiography (ECG) evolution in acute pericarditis. The initial ECG shows a diffuse ST-segment elevation and PR depression ( A ), which is followed by the resolution of the ST-segment elevation and then the presence of diffuse T-wave inversion ( B ), and lastly by improvement of all ECG changes ( C ).
