[Effect of somatic parameters on Frank's electrocardiogram in childhood].

Correlations were computed between 123 different electrocardiographic variables and constitutional parameters of 179 children aged seven to fourteen years using the Frank system. The constitutional parameters consisted of age, body weight, height, chest circumference and deviation from ideal weight related to height. The corrected orthogonal Ecg was automatically measured by a CD 3300 computer using the program of Pipberger. The results show that the greatest number of statistically significant correlations exist between Ecg variables and body height. In contrast to expectations, age takes only the second rank. Normal values of the Frank Ecg should be related to height not to age, at least in the studied age group.
