Objective To realize excellent remote medical treatment for patients.Methods The ECG monitoring module based on Bluetooth technology was designed.The ECG module and Bluetooth radio-frequency module,which possessed the function of data acquisition and simple processing,were connected through data wire to act as ECG terminal.By using C8051F020 and ROK 101 007 Bluetooth module,ECG Bluetooth transmission module read in HCI command through serial port,thus realizing mutual communication.VC++6.0 was used as developing tool to edit remote monitoring server programme running on the computers in monitoring center.Results ECG monitoring module could acquire ECG data in real time and transmit it to personal computers,and then send it to the monitoring center through Wide Band.In this way,real-time information exchange between doctors and users was realized.Conclusion This module makes full use of the advantages of Bluetooth technology and has strong practicability.
