Abstract

The T loops of 10 infants with congenital heart lesions producing combined ventricular enlargement were compared with those of normal controls and of infants with isolated right and isolated left ventricular enlargement. It was found that in biventricular enlargement the T loop might be normally placed (for age), or on the contrary it might reflect either the enlargement of the right or the enlargement of the left ventricle. A heretofore undescribed vectorcardiographic pattern of biventricular enlargement during the first year of life was shown. This consisted of the association of QRS changes characteristic of pure right ventricular enlargement coexisting with a T loop pointing anteriorly and to the right. The latter orientation was attributed to left ventricular strain.
