摘要
报告一种计算机辅助的起搏器参数自动测试系统,它可全自动地测试以下起搏器参数:脉冲幅度;脉冲宽度频率(基本起搏频率、磁频率、干扰转换频率、干扰起搏频率);灵敏度;逸搏间期;反拗期及芯片电流消耗等。系统根据国际标准组织1989年颁布的埋藏式心脏起搏器标准(ISO5841—1)和我国于1990年制订的埋藏式按需型心脏起搏器国家标准(GB,报批稿)进行检测,精心设计的硬件及软件系统使检测完全自动化,而且操作方便。文章同时给出了起搏器参数测量结果。
An IBM-PC aided testing system for parameters of cardiac pacemaker is described. It could measure pacemaker parameters, such as pulse rate (basic, magnetic, interfering conversion, interfering pacing), pulse interval, pulse width, pulse amplitude, sensitivity, sensing refractory period, pacing refractory period, escape interval, input impedance, time-averaged current drain etc. The parameters were tested according to International Stanand (ISO 5841—1) issued by International Stanand Organizaion in 1989 and National Standand (GB) of The People's Republic of China. The well developed hardware and software system made the testing process highly automatic and easy to use. The test results are also reported in the paper.
