摘要： 鉴于远程无线心电实时监护的特点及嵌入式系统计算速度慢、内存空间小的限制，提出由心电数据采集、存储、发送、加密、压缩和分析组成的心电数据处理机制。该处理机制已应用于远程无线多生理参数实时监测与分析网络平台，能够通过GPRS/CDMA/3G无线网络将心电数据完整、准确、实时地发送到监护服务器并同时在监护仪上得到分析结果。

Abstract: Limited by the computing speed and the memory space of embedded system, a new ECG data processing mechanism is proposed. It is based on the features of real-time ECG telemonitoring. It includes ECG sampling, ECG storage, ECG transmit, ECG encryption, ECG compression and ECG analysis. The processing mechanism is applied in the remote wireless multiple physiological parameter real-time monitoring and analyzing network platform. It can send the complete, accurate, real-time ECG data to the monitoring server through the GPRS/CDMA/3G wireless network and get the analysis result on the monitor.

Key words: ECG telemonitoring, circle buffer, encryption, ECG compression, QRS wave detection
