Isolated junctional tachycardia in a child after noncardiac surgery: an uncommon clinical presentation

Abstract

Isolated junctional tachycardia is rare in children but has been reported after cardiac surgery. To date, it has not been reported after noncardiac surgery. This report describes the case of a 3-year-old boy with no cardiac history who experienced transient junctional tachycardia after a right pyeloplasty. Medical therapy was not prescribed initially due to lack of symptoms. However, symptomatic junctional tachycardia recurred, prompting institution of oral beta-blocker therapy. Isolated junctional tachycardia should not be overlooked in the differential diagnosis of pediatric supraventricular tachycardia after noncardiac surgery.
