Objective. This study aims to describe the clinical, electrophysiological and therapeutic characteristics of pediatric patients with supraventricular tachycardia undergoing radiofrequency ablation. Materials and methods. Observational, descriptive, retrospective study of children admitted for supraventricular tachycardia treatment at the Instituto Nacional de Salud del Niño during 2018 to 2021. Results. Data from 62 procedures were collected, corresponding to 59 patients (mean age: 9.91 years, 61% male), 23% of procedures were performed in patients under 15kg, and two were in patients under 5kg. 63% of patients had a structurally normal heart, while 37% had some type of congenital heart disease, the most common being Ebstein’s anomaly. The most widely used group of drugs were beta-blockers, mainly propranolol. Among the arrhythmias treated, 21.7% had preexcitation Syndrome, 33.3% had ...
