Impact of Different Metabolic Indicators on Ventricular Repolarization Indices in Obese Children: A Case Control Study.

ABSTRACT:

Background

Obesity, insulin resistance, and dyslipidemia may impact ventricular repolarization in children.

Objectives

The study aimed to identify the relationship between various metabolic indicators and ventricular repolarization indices among obese children compared to healthy ones.

Methods

A case-control study included 90 children, divided into two groups: 45 obese children (cases) and 45 children with normal weight (controls). Electrocardiogram (ECG) readings were analyzed to calculate several parameters, including corrected QT (QTc), QTc dispersion (QTcd), JTc dispersion, and the TpTe interval, using 12-lead surface ECGs. Both groups were also assessed for lipid profiles, fasting plasma glucose (FPG), and serum insulin to calculate the Homeostatic Model Assessme
