Radiofrequency catheter ablation of right ventricular outflow tract tachycardia in a preschooler

A 3-year-old girl presented with a febrile illness complicated by right ven tricular outflow tract tachycardia, which persisted after resolution of the presumed viral infection. The tachycardia was intermittent, but was signif icantly exacerbated by exercise. Radiofrequency ablation (RFA) of the ectop ic focus was successfully performed and the child remains free of tachycard ia 12 months later. A review of the literature suggests that RFA in childre n is increasingly seen as a safe and convenient option for the treatment of supraventricular tachycardia, whereas the management of ectopic ventricula r tachycardia in pediatric practice has not been well defined.
