X线图像引导射频消融系统的研制

目的研制一种用于快速治疗心律失常的X线图像引导射频消融系统。方法通过X射线图像来引导消融导管,确定导管顶端的电极位置,在病灶处放出交电流,实现病灶的消融。并结合了多道电生理记录的功能,在进行消融手术的同时,可以观察和监控病人的电生理状况,保障病人的手术安全。结果一例隐性左侧旁道患者通过系统治疗,经过图像引导的消融后,A波与V波分开,获得了心脏消融的成功。结论通过X线图像的引导并结合多到电生理记录系统的射频消融系统,能有效快速的治疗简单的快速心律失常。

Development of X-ray image guided radiofrequency catheter ablation system

Objective To investigave the X-ray guided radiofrequency ablation system. Methods The ablation catheter was guided using the X-ray image so the location of electrode on top of the catheter can be fixed on. Alternating current was carried out at the focus to make the ablation. The multi-channel electrophysiology recorder was combined here to record the electrophysiology status before, during and after the surgery to ensure safety of the patient. Results One case was reviewed, which was treated with the X-ray guided radiofrequency ablation system. After the ablation, the A waves and the V wave were separated and the ablation surgery was successful. Conclusion Some simple and fast arrhythmia can be treated effectively by the above system.
