Design of a Cardiac Monitor in Terms of Parameters of QRS Complex

目的利用现有的常规心电图仪设计出一种能进行QRS波群参数测量的便携式液晶显示心电分析监护仪。方法该系统采用 80C1 96KB单片微型计算机为中央处理器 ,对实时心电信号进行数据处理和分析。结果它除了具有一般心电监护仪的性能外 ,还具有心律失常分析、心率变异分析、报警、手动测量、以及自动冻结、自动走纸记录等功能 ,能交、直供电 ,携带方便。在硬件上注重稳定性、低功耗和低成本 ;在软件上实行从顶至下的结构化设计。结论设计的监护仪通用性强、成本低 。

Objective To design a portable cardiac monitor system based on the available ordinary ECG machine and works on the basis of QRS parameters. Method The 80196 single chip microcomputer was used as the central microprocessor and real time electrocardiac signal was collected and analysized in the system. Result Apart from the performance of an ordinary monitor, this machine possesses also the following functions: arrhythmia analysis, HRV analysis, alarm, freeze, and record of automatic papering. Convenient in carrying, the system is powered by AC or DC sources. Stability, low power and low cost are emphasized in the hardware design; and modularization method is applied in software design. Conclusion Popular in usage and low cost made the portable monitor system suitable for use under simple conditions.
