BACKGROUND: There are not enough studies investigating the relationship between obesity and ECG abnormalities in children and adolescents. This study aims to investigate the relationship between obesity and electrocardiographic data in children and adolescents for early diagnosis to prevent arrhythmia or sudden death in later stages of life.
PATIENTS AND METHODS: A total of 65 children and adolescents with obesity applied to our pediatric endocrinology outpatient clinic with nonspecific complaints and without any known chronic illnesses; 76 healthy children and adolescents were included in the study. Anthropometric and laboratory data, blood pressure measurements, and 12-lead electrocardiography data of all participants were collected.
RESULTS: There was a statistically significant difference between the obese and the control group in terms of triglycerides, total cholesterol, high density lipoprotein, low density lipoprotein levels, and systolic blood pressure. According to electrocardiographic findings, there was a statistically significant difference between the two groups in terms of heart rate (p=0.008), PR duration (p<0.001), left ventricular hypertrophy (p=0.02), P maximum (p=0.04), P dispersion (p<0.001), QRS duration (p<0.001), QT minimum (p=0.007), QT maximum (p=0.03), QT dispersion (p=0.024), QTc minimum (p=0.002), QTc dispersion (p=0.003), Tp-e minimum (p=0.007), and Tpe maximum (p=0.003) variables.
CONCLUSIONS: There were significant differences between the electrocardiographic evaluation of obese group compared to the control group in our study, which may be associated with risk of cardiac arrhythmia. These differences require monitorization in terms of cardiac arrhythmia and risk of sudden death. Further studies with longer follow-up time are needed to support the potential clinical outcomes of our findings.
