依据1990年埋藏式按需型心脏起搏器国家标准(报批稿),兼以收取具有代表性的生产厂家测试标准,研制了起搏器测试系统。该系统是在286微机内加一块接口板,微机外连一块专用板,软件采用TURBO PASCAL调用8088/8086宏汇编实现的。测试系统包括四种常用的测试波测试感知灵敏度。在文中讨论了脉冲幅度、脉宽是否从中点开始测量并不影响精度,并提出了应测试起搏器感知特性曲线的看法,供商榷。
According to the 1990 national standards for buried type on-demand pacemakers (draft for approval), and to collect representative of the manufacturer test standards, developed a pacemaker test system. The system is in the 286 microcomputer plus an interface board, the computer is connected with a special board, the software uses TURBO PASCAL call 8088/8086 macro assembly to achieve. The test system includes four commonly used test wave test perceptual sensitivities. In this paper, it is discussed whether the pulse amplitude and pulse width measure from the midpoint does not affect the accuracy. The view that the perceptual characteristic curve of pacemaker should be tested is put forward for discussion.
