我院使用了一台中科院英特公司生产的KYKY－ZFJll型射频消融仪，本机针对心动过速的病人进行治疗，首先将几根导管由血管插入心脏，自导管末端电极取出心电信号，输出给人导生理记录仪，通过观察心电信号的变化，找准发病部位即靶点，然后扳动3组切换开关（此3组切换开关扳向一
Our hospital used a KYKY-ZFJll radiofrequency ablation instrument produced by the Intel Corporation of the Chinese Academy of Sciences. This machine treats patients with tachycardia. First, several catheters are inserted from the blood vessels into the heart, and the ECG signals are taken from the end of the catheter. The output is given to a human physiological recorder.
