中国人民解放军空军总医院内二科最近应用美国Honerwell V12生理记录仪,设计侧位气囊食道电极导管。将此食道电极位于房室沟水平记录希氏束电图获得成功。收集到的希氏束信号先经高通-低通滤波选择(100—500HZ),然后经初级和次级放大技术,总增益约100—10,000倍。放大后的希氏束信号转输入多导记录仪。为了证实经食道电极记
People’s Liberation Army General Hospital Air Force recently applied the United States Department of Honerwell V12 physiological recorder, lateral airway esophageal catheter design. The esophageal electrode is located in the atrioventricular groove horizontal His bundle beam was successful. The collected His bundle signal is first selected by high-pass-low pass filter (100-500HZ) and then by primary and secondary amplification techniques with a total gain of about 100-10,000 times. The amplified His bundle signal is transferred to the multi-conductor recorder. In order to confirm the transoesophageal electrode mind
