Background: This study investigates PR interval variations in asymptomatic obese young
adults to assess their potential cardiovascular risk and predict future cardiovascular diseases.
A total of 150 obese individuals (BMI ≥ 30 kg/m²), aged 18–39 years, were compared with 150
age- and sex-matched healthy controls (BMI < 22 kg/m²). Anthropometric indices including
Body Mass Index (BMI), Body Surface Area (BSA), and Waist-Hip Ratio (WHR) were
calculated. Vital signs such as pulse rate, systolic blood pressure (SBP), and diastolic blood
pressure (DBP) were recorded. A 12-lead ECG was performed after 10 minutes of rest, and PR
interval was measured in milliseconds. Data were expressed as mean ± standard deviation and
analyzed using an unpaired t-test.
