Biochemical Markers and Hypertension in Children.

INTRODUCTION Hypertension is one of the most studied risk factors for cardiovascular disease in adults; in children and adolescents, its global prevalence changes with age, from 1%-3% in children to 3.2% in adolescents. In adults, in addition to hypertension, several biochemical markers of cardiovascular risk have been identified.

[P wave dispersion increased in childhood depending on blood pressure, weight, height, and cardiac structure and function].

Introduction: Increased P wave dispersion are identified as a predictor of atrial fibrillation. There are associations between hypertension, P wave dispersion, constitutional and echocardiographic variables. These relationships have been scarcely studied in pediatrics.

Dependence of P-wave dispersion on mean arterial pressure as an independent hemodynamic variable in school children.

Introduction: The relationship between diastolic dysfunction and P-wave dispersion (PWD) in the electrocardiogram has been studied for some time. In this regard, echocardiography is emerging as a diagnostic tool to improve risk stratification for mild hypertension.

Objective: To determine the dependence of PWD on the electrocardiogram and on echocardiographic variables in a pediatric population.
