一种能实现QRS波群参数测量的心电监护仪设计

以研究适合我国国情、利用现有的常规心电图仪设计出一种能进行QRS波群测量的便携式液晶显示心电分析监护仪。该系统采用80C196KB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。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。所实现的监护仪通用性强、成本低,尤其为开拓我国监护仪事业有一定的参考价值。

The design of a cardiac monitor able to measure QRS parameter

Based an ordinary ECG, this paper deals with a portable monitor system able to measure the values of QRS. With a liquid crystal display (LCD), this monitor is suitable for China's special condition. Besides developing the overall scheme of the system, this paper also performs the designs for the hardware and software. The 80196 single chip microcomputer is taken as the central microprocessor to process and analyze the realtime ECG signals. With the performances of the ordinary monitor, this monitor also has such functions as arrhythmia analysis, HRV analysis, alarm, self-freeze and paper self-advance. Being convenient to carry, this monitor can be powered by alternate current (AC) or direct current (DC). Stability, low power consumption and low cost are emphasized on in the hardware design and structured design is applied to the software design. With a high versatility and a low cost, this monitor has a valuable reference to China's monitor.
