Introduction: The treatment of cardiac arrhythmias and conduction is one of the most difficult sections of clinical pediatrics. This is due to the variety of clinical forms of arrhythmias, the lack of a common understanding of the mechanisms of their occurrence, and, therefore, generally accepted treatment methods.
Materials and Methods: We performed 60 radiofrequency ablation procedures for 48 preschool patients with various types of arrhythmias, among them 25 children with WPW syndrome, 14 with atrial tachycardia, 3 with atrioventricular reciprocal tachycardia, 4 with ventricular tachycardia, 2 with extrasystoles. Radiofrequency ablation of arrhythmias in preschool children is effective and relatively safe.
Results: Factors associated with a high risk of recurrence after successful RF ablation is the minimally effective RF exposure parameters used to reduce the risks of various complications.
Conclusion: The use of navigational mapping in children significantly reduces radiation exposure during electrophysiological studies and radiofrequency ablation and reduces the potential risk of long-term complications.
