我院放射科导管室在做风湿性心脏病二尖瓣狭窄、布—加氏综合征球囊导管扩张手术时,出于心脏、血管内压力的波形记录不下来,造成手术完成时间延长,对了解瓣膜、下腔静脉狭窄段扩张程度带来一定困难.为了测压及心电监护人员免受不必要的放射线照射,我们人为地延长了SBQ—Ⅰ型四踪生理示波器及心脏去颤起搏器与X线机管球的距离,采用隔室测压及心电监护.但由于延长了连接线,致使压力、心电信号失真.虽然满足这些条件的综合性仪器在市场上可以买到,但是价格太高,且有些仪器与其他仪器的性能不易匹配,较难被一般医院所接受.为此,我们根据临床需要设计出压力、心电匹配器,经一年半临床使 Our hospital radiology catheter room in rheumatic mitral stenosis, Budd-Chiari syndrome balloon catheter dilatation surgery, out of the heart, intravascular pressure waveform record does not come down, resulting in the completion of the surgery, the right To understand the valve, the expansion of the inferior vena cava stenosis has brought some difficulties.In order to manometry and ECG monitoring personnel from unnecessary radiation, we artificially extend the SBQ-Ⅰ type four trace physiological oscilloscope and cardiac defibrillation pacing X-ray machine and the distance between the tube, the use of compartment manometry and ECG monitoring.But due to the extension of the connection line, resulting in pressure, ECG distortion.Although meet the comprehensive conditions of these instruments are available on the market, But the price is too high, and some instruments are not easy to match the performance of other instruments, more difficult to be accepted by the general hospital.To this end, we designed according to the clinical needs of pressure, ECG matcher, after a year and a half
