房性心动过速 (简称房速 )的射频消融治疗 ,是通过消融导管将射频电流输送到引起房速的靶病变组织 ,产生凝固性坏死 ,从而消除房速基质 ,使房速得以根治。由于射频消融术在房速治疗中具有创伤小、成功率较高、并发症少等优点 ,加之现有抗心律失常药物对房速的长期疗效并不十分 Atrial tachycardia (hereinafter referred to as atrial tachycardia) radiofrequency ablation treatment is the radio frequency current through the ablation catheter delivery to the target lesion tissue causing the tachycardia, resulting in coagulation necrosis, thereby eliminating the tachycardia matrix, so that the atrial tachycardia can be radical. Due to the advantages of radiofrequency catheter ablation in the treatment of tachycardia with less trauma, higher success rate, fewer complications and the long-term efficacy of the existing antiarrhythmic drugs on the tachycardia,
