[Diagnosis and treatment of common pediatric supraventricular tachycardias].

The incidence of paediatric supraventricular tachycardias is approximately 0.1-0.4%. AV node and AV reentrant tachycardias represent the most common supraventricular tachycardias in children. Atrial ectopic tachycardias are the second most common group of pediatric arrhythmias with a predominance in younger children. All these arrhythmias may result in a significant morbidity and necessitate therapy. During the last decade the widespread use of newer antiarrhythmic agents and the invention of radiofrequency catheter ablation have revolutionized the treatment of supraventricular tachycardias in children. A thorough knowledge of these various treatments options is essential to achieve a safe and effective management of supraventricular tachycardias in children. This article focuses on diagnostic and therapeutic aspects of the most frequent supraventricular tachycardias.
