冷冻消融在治疗阵发性室上性心动过速中的应用

摘要

Paroxysmal supraventricular tachycardia (PSVT) is one of the frequent cardiovascular diseases.In recent years, cryoablation has become a research hot spot for PSVT treatment.Theoretically, its operability and safety are both better than those of radiofrequency ablation.Cryoablation can significantly reduce risk of ablation complications, but how to reduce recurrent rate after cryoablation is still a problem in the future.The present article made a review on main therapeutic methods of PSVT, especially application of cryoablation.%阵发性室上性心动过速(PSVT)是临床上常见的心血管疾病急症之一.近年来,冷冻消融技术已逐渐成为PSVT治疗方法的研究热点之一,理论上其可操作性和安全性均优于射频消融,在很大程度上降低了消融并发症的发生风险,然而如何降低冷冻消融术后复发率仍是未来需要攻克的难题.本文就目前治疗PSVT的主要方法,特别是冷冻消融的应用作一综述.
