title: Ablation of tachyarrhythmias in pediatric patients.
abstract: OBJECTIVE
  Radiofrequency (RF) ablation treatment for tachyarrhythmias has been available only for the past 15 years. The success rates have been excellent with a very low frequency of complications. Because of this efficacy, the use of RF ablation in children has become standard of care even though long-term data are unavailable. In this review, common tachyarrhythmias and their current treatments in children will be discussed.
  
  
  RESULTS
  Novel electrophysiology technologies such as electroanatomic mapping and sophisticated ablating catheters have improved success rates and decreased complications. The improvement is also due to better understanding of the mechanisms and etiologies of tachyarrhythmias. Both have positively impacted success rates and have made more complicated tachyarrhythmias treatable with ablation.
  
  
  CONCLUSIONS
  The technologic advances in ablation and improved understanding of tachyarrhythmias over the past 15 years have greatly improved outcomes in ablative treatment of tachyarrhythmias in children. In most cases this method of treatment is the preferred first-line approach to symptomatic tachyarrhythmias in children.
