In the quiescent stage of rheumatic heart disease, however, standard leads often yield normal tracings in children with enlarged hearts and obvious myocardial involvement.
In adults, precordial, as well as standard, leads have given valuable information in regard to hypertrophy of individual chambers of the heart.1 It was thought possible, therefore, that this technic might also be useful in studying rheumatic children and adolescents.
