Complete atrioventricular block in an adolescent with acute rheumatic fever: a case report

Prolonged atrioventricular conduction (first -degree heart block) is a well-known symptom of ARF, occurring in one -fifth to three -fifths of patients. This condition is a minor criterion for diagnosing ARF based on Jones's criteria. Advanced conduction delay, such as a second-degree or a complete atrioventricular (AV) block, is a rare condition of ARF that can occur before symptoms like carditis, polyarthritis, and Sydenham chorea appear. We present a case of ARF in an adolescent with complete AV block.
