1、前言

心电图 (ECG) 是心脏疾病诊断的重要手段。常规心电图是病人在静卧情况下由医院的心电图仪记录的短时间心电活动,由于心脏病发作带有很大的偶然性和突发性,所以在非发作期做常规心电图检查获取疾病信息的几率很低。因此,将心电监护从病床边、医院内扩展到家中,实现实时远程监护具有重要的现实意义。互联网尤其是无线网络的迅速普及促使嵌入式技术应用的条件日趋成熟,此外,心电监护对心脏病诊断的重要性也使得远程监护也具有现实的可能性。

2、方案概述

Ameya360 心率监测器解决方案设计了一套实用的便携式移动心电监护系统。通过该系统可以随时随地将患者的心电信号通过 GPRS 网络无线发送到设在医院的 PC 机上,或者将心电数据先存储在本系统中,然后再通过 USB 实现高速回放。系统由心电监护仪、通信网络和监护中心三部分组成。在进行总体硬件设计时,以高性能微处理器为核心,利用外部接口扩展了 512K 的并行 Flash 和 512K 的 SRAM,存储空间达到 1M,并扩展了 USB 接口。利用串行接口扩展了串行 Flash、A/D 转换和无线模块 MC35。能够在计算机屏幕上准确地描绘出心电波形,经中国医科大学附属二院的医生认定,可作为临床诊断依据;本系统实用性强,且体积小、经济方便。患者可随时随地对心脏进行实时监护,而不受时间和空间限制;本系统所具有的无线传输功能,可以实时地把心电数据传送给医院供医生诊断,极大地提高了急救效率。
