The 12-lead electrocardiogram in patients with acute pericarditis classically shows widespread upward concave ST-segment elevation and PR-segment depression. The electrocardiographic abnormalities may evolve through four phases: diffuse ST-segment elevation and PR-segment depression (stage I); normalization of the ST and PR segments (stage II); widespread T-wave inversions (stage III); and normalization of the T waves (stage IV).
For Acute PE :- S1Q3T3 is indicative of PE
