【摘要】 介绍了一种采用AT89C51单片机和图形LCD显示器技术而设计的便携式急救心电监护仪。它能提供实时、准确、高清晰度显示的心电(ECG)波形和主要心电参数的数字显示,这些参数通过ECG自动分析处理技术得到的。该仪器还有心律失常监护、心肌梗塞贴药急救、报警参数设置和记录报警时的心电信号供医生作回顾分析等多种功能,具有体积小、成本低的优点,特别适用于家庭医护以及急救情况下的临床诊断和监护。文中给出了仪器的硬件、软件设计。更多还原

【Abstract】 This dissertation describes a portable emergency ECG monitor developed by using the single chip computer AT89C51 and the liquid crystal graphic display(LCD). It can provide real-time, accurate, high resolution display of ECG waveforms and numeric displays of the main ECG parameters through the automatic ECG analyzing and processing technology. The instrument also has various functions, such as arrhythmia monitoring, emergency treatment of acute myocardial infarction(AMI), alarm parameters setting and abnormal ECG waves saving to provide historical data for doctors. It is a compact and inexpensive monitor and is especially suitable for diagnosis, monitoring in mergency and home monitoring. The hardware and software design of the monitor is presented too.更多还原
