摘　　要：为克服传统的有导联线动态心电监测装置导线连接复杂,影响心电信号采集的质量,使患者受限、产生束缚感等不足,设计了一种基于ZigBee的无导联线动态心电监测样机。该系统主要由信号采集模块和无线传输模块组成,采集到的心电信号通过CC2530自带的A/D转换成数字信号并通过无线模块发送,经ZigBee无线传输后,由接收模块接收心电数据并通过串口上传至PC机实时显示。给出了硬件电路的设计方案及软件程序流程图,并在实验室环境下对该样机进行了测试,实现了心电信号的无导联线监测和心电波形的实时显示。该样机具有功耗低、成本低、重量轻和体积小等特点,心电波形失真度较小,可满足临床分析与诊断的要求。The traditional dynamic ECG （ElectroCardioGram） monitoring device is complex due to many wire connection. The patient＇s body is limited resulting in a sense of restraint and the quality of ECG is affected. To o- vercome these drawbacks,we designed a wireless dynamic ECG monitoring device based on ZigBee. The device has the advantages of low power consumption, low cost, light weight, and small size. It is mainly composed of a signal acquisition module and wireless transmission module. The acquired ECG signals are converted to digital signals by the A/D in CC2530, and sent through the wireless module. Via ZigBee wireless transmission, the ECG signals are received by receiving module and uploaded describes the design of the hardware circuit, and gives to PC machine in serial for real-time display. This study the flow chart of software program. The device has been tested in the laboratory, and the real-time ECG waveforms show that the achieving ECG signals with little distor- tion can be used for clinic analysis and diagnosis.
