Interpretation of the findings, therefore, depends on the clinical context and … WebThe T wave represents ventricular repolarization. T waves are normally positive, but negative T waves are normal findings in leads aVR and V 1 (and in young people, in V 2). The causes of pathologic T-wave inversion include myocardial ischemia and infarction, ventricular strain, and treatment with digoxin.
