ABSTRACT
INTRODUCTION:
The study of arterial hypertension risk factors in children guarantees the establishment of health policies to avoid complications associated with this illness in the future. The highest values of P-wave dispersion during sinus rhythm are pointed as predictors of atrial fibrillation in adulthood since there is an association between arterial hypertension, P-wave dispersion and left ventricular hypertrophy. The aim of this study was to determine the relationship between blood pressure, left ventricular mass index and P-wave dispersion in the pediatric population. POPULATION ANDMETHODS:
In the frame of the PROCDEC II project, children from 8 to 11 years old, without known heart conditions were studied. Arterial blood pressure was measured in all the children; a 12-lead surface ECG and an echocardiogram were done as well.RESULTS:
Left ventricular mass index mean values for normotensive (25.21 ± 5.96 g/m²) and hypertensive (30.38 ± 7.39 g/m²) children showed significant differences (p= 0.000). The mean value of the left atrial area was significantly different (p= 0.000) when comparing prehypertensive (10.98 ± 2.23 cm2) and hypertensive (12.21 ± 1.27 cm²) children to normotensive ones (10.66 ± 2.38 cm²). The correlation of P-wave dispersion and the left ventricular mass index showed an r= 0.87 and p= 0.000.CONCLUSIONS:
P-wave dispersion is increased in pre- and hypertensive children compared to normotensive ones. A dependence of the P-wave dispersion of the left ventricular mass index was found in hypertensive children.
