ABSTRACT

Incidental severe bradycardia in children requires structured evaluation. A 4-year-10-month-old boy presenting with upper respiratory tract infection (URTI) symptoms was found to have complete atrioventricular (AV) block. Holter monitoring demonstrated persistent AV block (average heart rate 44 bpm, minimum 34 bpm). Echocardiography revealed structurally normal cardiac anatomy with preserved systolic function (EF 66%, FS 36%). After systematic exclusion of reversible causes, a single-chamber permanent pacemaker was implanted. This case emphasizes structured diagnostic reasoning and cautious interpretation of pediatric conduction disorders.
