The natural history and therapy of supraventricular tachycarida (SVT) in childhood vary according to the mechanism of tachycardia, emphasizing the importance of understanding the electrophysiologic diagnosis before recommending therapy. The most common types of SVT in childhood involve an accessory connection, atrioventricular nodal reentry tachycarida and, less frequently, primary atrial tachycardia. As the mechanisms vary according to age, long-term therapy should consider the mechanism of SVT, patient age and symptoms. In many cases no chronic therapy is necessary. This article summarizes the common mechanisms and treatment options of SVT in childhood.
