All of the following statements regarding the ECG changes in acute pericarditis are true, except:
In acute pericarditis, T wave inversion occur only after the ST segment return to the baseline level. Ref: Practical ECG Interpretation: Clues to Hea Disease in Young Adults By George Stouffer, Page 124
Sinus tachycardia is a common finding
PR segment depression is present in majority of patients
Global ST segment elevation is seen in early pericarditis
T wave inversions develop before ST elevation return to baseline
