Abstract

Objective: Electrocardiography (ECG) is a simple and useful tool for the early detection of cardiac conduction abnormalities. In students, these abnormalities are often asymptomatic, yet some cases may carry a potential risk of arrhythmias or future cardiovascular events. Objective: To evaluate conduction abnormalities on electrocardiograms in healthy university students. Subjects and Methods: A cross-sectional study was conducted on 292 students at Hong Bang International University. Results: Conduction disorders of the heart were notable, accounting for 10.6% of the total healthy students. One case of incomplete left bundle branch block was recorded. The prevalence of complete right bundle branch block was higher in males than in females. Conduction disorders were more common in the group over 25 years old compared to the younger group (16.8% vs. 10.2%). Students who were underweight or overweight showed higher rates of conduction disorders. The underweight and obese groups were notable for a high prevalence of short PR interval (5.7% and 4.5%, respectively). The overweight group recorded several cases of atrioventricular block and incomplete right bundle branch block (5.4%). Conclusion: The study concludes a 10.6% prevalence of cardiac conduction abnormalities in healthy students, which is higher than most comparable international studies. The main abnormalities are short PR, RBBB, and AV block, with frequency trends observed across gender, age, and BMI.
