[Non-invasive treatment of tachycardias during childhood].

In principle tachycardias during childhood do not differ from those in adulthood but they present with a significant age-dependency. Additionally the clinical presentation has a broad spectrum related to the different ages, from the neonatal period until adolescence. If congenital heart disease is present the hemodynamic compromise may be accentuated. This paper describes the diagnostic and therapeutic approaches to pediatric tachycardias with focus upon the age dependent aspects and the presense of congenital heart disease, either native or postoperative.
