[The electrocardiogram in infantile arterial hypertension].
ECG traces from 60 children aged 10-14 yr with hypertension were examined to see whether this condition itself was enough to alter the parameters in a statistical comparison with the traces for 19 normotensive children of the same age. Some statistically significant differences were noted in: the deviation of the P wave axis, increased left ventricle activation time, frequency and QTc segment, presence of anticlockwise rotation on the longitudinal plane and junctional rhythms. These support the view that changes in these parameters is not dependent on the concomitance of other diseases, but due to hypertension itself.
