The informational content of these data can be maximized by treating each angle as a point on a plane whose distance from the origin is equal to the magnitude of its vector. These points can be resolved into their horizontal and vertical coordinates. The coordinates are linear values and can(More)
The heart is known to participate in the adolescent growth spurt. A peak increase in transverse diameter coincides with peak height velocity during pubertal maturation. The effects of maturation on the adolescent ECG were explored using sexual maturity rating (SMR) as a marker. ECGs were obtained from 751 patients 8 to 20 years of age seen for routine(More)
