Isolated junctional tachycardia occurred in a 9-year-old girl with non-rheumatic fever streptococcal pharyngitis and resolved following treatment with amoxicillin.
Case Report (n=1)
Isolated junctional tachycardia can occur in children with streptococcal pharyngitis without acute rheumatic fever and may resolve with appropriate antibiotic therapy.
Isolated junctional tachycardia may occur with streptococcal pharyngitis; this case leaves open a non-rheumatic link for prospective study.
Accelerated junctional rhythm has been reported in children in the setting of acute rheumatic fever; however, we describe a hitherto unreported case of isolated junctional tachycardia in a child with streptococcal pharyngitis, not meeting revised Jones criteria for rheumatic fever. A previously healthy, 9-year-old girl presented to the emergency department with complaints of sore throat, low-grade fever, and intermittent chest pain. She was found to have a positive rapid streptococcal antigen test. The initial electrocardiogram showed junctional tachycardia with atrioventricular dissociation in addition to prolonged and aberrant atrioventricular conduction. An echocardiogram revealed normal cardiac anatomy with normal biventricular function. The patient responded to treatment with amoxicillin for streptococcal pharyngitis. The junctional tachycardia and other electrocardiogram abnormalities resolved during follow-up.

Bansal et al. (2016) conducted a case report in Junctional tachycardia and streptococcal pharyngitis (n=1). Streptococcal pharyngitis was evaluated on Resolution of junctional tachycardia and electrocardiogram abnormalities. Isolated junctional tachycardia occurred in a 9-year-old girl with non-rheumatic fever streptococcal pharyngitis and resolved following treatment with amoxicillin.
