Abstract: This paper introduces ECG data network transmission based on GPRS, ECG data is transmitted to the center of ECG monitor which is accessed to GPRS network. Doctors analyze and diagnose the ECG data and transmit the conclusion to consumers. While in the transmission process of ECG data, node encryption and data encryption are realized, it has real-time, synchronous and ECG characteristics without distortion. The remote monitoring and timely diagnosis of ECG for the patients outside the hospital are realized.

Key words: synchronous, GPRS, network transmission, encryption
