AHA/ACCF/HRS Recommendations for the Standardization and Interpretation of the Electrocardiogram. Chou’s Electrocardiography in Clinical Practice: Adult and Pediatric, 6eĢ. The ST segment elevation in early repolarization resolves when the person exercises.Įarly repolarization, unlike pericarditis, is a benign ECG finding that should not be associated with any symptoms.ġ. Another way to describe this would be that the ST segment elevation is less than 25% of the T wave amplitude in early repolarization. At times, pseudonormalization of T waves may be the only ECG change seen during acute myocardial ischemia, however it can also be an early sign of preceding ST. These findings occur in progressive stages, all of which are seen in about 50 of cases of. The ratio of the T wave amplitude to the ST elevation should be greater than 4 if early repolarization is present, meaning the T wave in early repolarization is usually 4 times the amplitude of the ST segment elevation. Pericarditis, or inflammation of the pericardium, has typical ECG findings.

However, three things may help to distinguish pericarditis from early repolarization: The ST segment elevation seen in early repolarization is very similar ― diffuse and concave upward. Note: The ECG changes with pericarditis must be distinguished from those of early repolarization. Stage IV: T waves return to the upright position, and thus the ECG is back to normal. Stage III: T waves are inverted, and the ECG is otherwise normal. Stage II: ST segment elevation and PR depression have resolved and T waves may be normal or flattened.
