A dynamic ECG system with teletransmitting and receiving function by telephone is introduced. And it consists of the ECG recorder carried by patients. The ECG receiver used in hospital and the PC puter used to analyze ECG signals. The principle of the designed system is described. And the system software for the telereceiving and analyzing of the ECG signals is introduced. This system has realized telereceiving and analyzing of ECG based on conventional dynamic electrocardiogram.At present. Dynamic ECG systems used in clinic can not telereceive ECG signals, and the patients have to go to hospital for their ECG diagnosis. With the development of puter network and munication technology. It is possible for hospital to offer the service of heart health with longdistance. A dynamic ECG system with function of telereceiving ECG is designed in this paper. And ECG signals are teletransmitted by telephone network.The dynamic ECG system designed in this paper consists of the ECG recorder. The ECG receiver and the PC puter. And its structure is showed in the following picture.ECG recorderECG receiverPCputerRS232RS232Telephone line圖C1The dynamic ECG system can continuously record and monitor ECG signals from human body using portable recorder. And the recorded ECG signals can be received and analyzed by PC puter. The structure of ECG recorder is showed in the next.ECGamplifierA/DMSP430D/AModemPoweramplifierLoudspeakerTelephoneTelephone networkECG圖C2The ECG receiver is the connection bridge between PC puter and the ECG recorder. And it receives the modulated ECG signal from the recorder through telephone transmitting. The structure of ECG receiver is showed in the next.TelephoneSignal sample and AmpliferMSP430PCRS232Telephonenetwork圖C3The puter receives and analyzes the demodulated ECG signal from the receiver via RS232 interface. The recorder can directly be connected to the puter via RS232 for its initialization. And puter can directly receive the ECG signal from the recorder via RS232 interface. Doctors can analyze ECG signal and diagnose heart diseases in PC (Such as arrhythmia. ST segment deflection etc.).The design tasks of entire systematic software lie in the software design of the ECG recorder, ECG receiver and the puter. And it mainly consists of database management module. Recorder initialization module. ECG receiving and display module. And ECG analysis module with function of arrhythmia analysis, ST segment analysis and heart rate variation (HRV) analysis. The application software in PC is designed with the use of Visual Basic in Windows 98.The dynamic ECG system described in the paper not only have conventional function of electrocardiogram diagnosis. And but also can receive ECG signal by telemunications. The recorder can sample two channel ECG signals from VI and V5 leads at the sane time with the frequency of 500 Hz. In order to analyze the ECG signals. Pa
