Juvenile T waves (a study of 100 normal subjects).

"Juvenile pattern" of T wave inversion in the precordial leads of electrocardiogram was studied in 100 normal healthy Indians of 0 to 70 years of age in both sexes. Incidence of such pattern was observed in 25 subjects upto 19 years of age. Persons of weight/height ratio less than 30% had higher incidence of juvenile T waves. Maximum incidence (48%) of juvenile T waves was observed in the annual income group of Rs. 15000/-. Exercise ECC showed slight flattening of the inverted T waves in V1 to V3 leads in eight subjects only.
