Comparing withtraditional Holter system, the advantage of ECG Remote Monitor system isthe ability to help doctor to obtain patients? ECG more quickly and pletely,which make it be more suitable to monitor heart disease which is chronic bute on all of a sudden. If PDA is introduced to this system, to obtainpatients? realtime ECG will be more conveniently. PDA provides a mobileand convenient information process service to doctors. With the help of PDA,doctors can obtain patients? ECG anytime and everywhere. PDA software System of Realtime ECG Monitoring is a subsystem ofECG Remote Monitor system. In this paper, the role of PDA software Systemplays in ECG Remote Monitor system is introduced firstly, and then thearchitecture of PDA software system. Thirdly, munication model andmunication protocol of the system are described. The author is engaged in the studying and manufacturing of portable ECGmonitor and its system based on AT89C52 low power MCU. According to thecharacteristic of human39。s ECG signal, an excellent ECG signal sampling systemwas designed. Further more, The monitor uses low power 8bits, single chipmicroputer AT89C52 and bulk Flash memory to record, analyst, and processthe ECG signal at real time. The monitor uses LCD to show the ECG wavesdetected. Cooperated with buttons, it provides amicable Chinese menu and makesoperation simple and convenient, and the ECG data can be transmitted toPersonal Computer by serial RS232 interface. This monitor can work stably andreliably for a long time, and with some excellencies such as mini volume, bulkmemory, low power, etc. It is convenient to be taken with and used. By use of the assemble language in programming, the author also makes anECG autoanalysis software module. This software is convenient to be used aswell as has friendly interface. With the excellent ECG signal sampling system,the LCD can show the ECG waves detected at real time.
