Progress in the application of radiofrequency catheter ablation in children

Abstract

Tachyarrhythmia is a common type of arrhythmia in children.Continuous of frequent tachy cardia can bring serious harm to children's physical and mental health.With the help of electrophysiological study,electrophysiological mechanisms of various arrhythmias have been stated constantly,while the medical technology develops rapidly.The treatment strategy in pediatric arrhythinia has undergone major reforms,and radiofrequency catheter ablation has come into being.Through the thermal efficiency of the radiofrequency current,radiofrequency catheter ablation can damage the arrhythmia foci or block the atrioventricular reentrant pathway,so achieve the purpose of cure.The clinical application of radiofrequency catheter ablation can avoid the inconvenience of antiarrhymic drugs.Comprehensive assessments of the impacts and possible prognosis should be achieved by clinicians.Strict indications are very important.Currently the ablation has matured in atrioventricular re entrant tachycardia,atrioventricular nodal reentrant tachycardia,ventricular tachycardia,atrial tachycardia and atrial flutter,with high successful rate and low recurrence rate.Complications are closely related to the experience of the surgeon.
