N2 - Even though positive T waves in the right chest leads of infants have been considered mainly to be due to right ventricular enlargement, there are still other causes which can produce similar changes. The spatial vectorcardiographic significance of such conditions has been studied in normal as well as in abnormal hearts. The morphology, rotation, and orientation of the T loop has been analyzed during the immediate neonatal period; in right, left, and biventricular enlargements, as well as in malnourished children with diarrhea. The differential diagnosis between the various abnormalities is stressed, based mainly in the changes in the repolarization complex.
