Holter monitoring detects complex AV block and ventricular arrhythmias in acute rheumatic fever.
Case Report (n=1)
No
Complex conduction abnormalities and ventricular arrhythmias, including non-sustained ventricular tachycardia, can manifest in pediatric acute rheumatic fever even without severe valvulitis.
May prompt arrhythmia monitoring in pediatric rheumatic fever; hypothesis-generating for prevalence and outcomes without valvulitis.
A 15-year-old boy was admitted to the emergency department with arthralgia of the knee. He was diagnosed with acute rheumatic fever based on clinical examination, electrocardiography, echocardiography, and elevated inflammatory markers including C-reactive protein, erythrocyte sedimentation rate, and anti-streptolysin O titre. First-degree and second-degree Mobitz type 1 atrioventricular blocks, moderate frequency uniform ventricular premature beats, as well as non-sustained ventricular tachycardia, were detected on 24-hour Holter electrocardiography monitoring.

Çaran et al. (2026) conducted a case report in Acute rheumatic fever (n=1). 24-hour Holter electrocardiography monitoring was evaluated on Detection of cardiac arrhythmias. 24-hour Holter monitoring in a 15-year-old boy with acute rheumatic fever detected 1st- and 2nd-degree Mobitz type 1 AV blocks, premature ventricular beats, and non-sustained ventricular tachycardia.
