Radiofrequency current ablation successfully eliminated the ectopic automatic focus while preserving normal atrioventricular conduction, with the patient remaining tachycardia-free at 7 months.

Does radiofrequency ablation successfully treat refractory automatic junctional tachycardia while preserving AV nodal conduction in a pediatric patient?
Radiofrequency ablation can be a safe and effective treatment for refractory automatic junctional tachycardia in pediatric patients, preserving normal AV nodal conduction.
Automatic junctional tachycardia is frequently refractory to medical management and difficult to treat with nonpharmacological methods. A 12-year-old female with symptomatic, refractory automatic junctional tachycardia is reported. Earliest atrial activation during supraventricular tachycardia was in the posterior portion of the intraatrial septum. The patient underwent electrophysiological study and successful radiofrequency current ablation of the ectopic automatic focus within the atrioventricular junction. Normal atrioventricular junctional conduction was maintained, and at 7-month follow-up the patient has been free of tachycardia.
Ehlert et al. (Fri,) conducted a case report in Automatic junctional tachycardia (n=1). Radiofrequency current ablation was evaluated on Freedom from tachycardia and maintenance of normal atrioventricular junctional conduction. Radiofrequency current ablation successfully eliminated the ectopic automatic focus while preserving normal atrioventricular conduction, with the patient remaining tachycardia-free at 7 months.
