摘　　要：心房颤动又称房颤,是一种常见的心律失常,其发病率随着患者年龄的增长而升高。导管消融被认为是治疗房颤、维持窦性心律的有效手段,常见的消融技术包括射频消融、冷冻消融等。但现有导管消融技术存在"零和效应",临床上难以控制最优剂量。本研究中,提出了脉冲电场消融治疗房颤的新方法,有效解决了温度消融的"零和效应"问题。临床应用结果表明,该技术有效克服了现有温度消融技术的不足,可以形成持久的肺静脉隔离。Atrial fibrillation,also known as atrial fibrillation,is a common cardiac arrhythmia,and its incidence increases with age.Catheter ablation is considered to be an effective means to treat atrial fibrillation and maintain sinus rhythm.The common ablation technologies are radiofrequency ablation and cryoablation.However,the existing catheter ablation technology has a"zero-sum effect",and it is difficult to control the optimal dose clinically.In this study,a new method of pulsed electric field ablation for atrial fibrillation was proposed,which effectively solved the"zero-sum effect"problem of temperature ablation.The clinical application results show that the proposed technology effectively overcomes the shortcomings of existing temperature ablation,and can form durable pulmonary vein isolation.
