Research On A Long-distance ECG Monitoring System Based On PDA

It's reported that there were 15,300,000 people died of cardiopathy on the world in 2004, and the cardiopathy has become the main disease that does harm to the peoples'health. So the doctors in most countries begin to pay more attention to the diagnosis and the treat of the cardiopathy. Under this condition, knowing the state of the patient in time is very important to avoid the sudden death caused by the cardiopathy. In order to provide a telecardiology service to patients in real-time mode,which is not affected by any factors,such as time and place,a design of ECG Tele-monitoring system based on PDA is proposed.The whole system consists of the portable ECG signal collection terminals and a hospital monitoring center. And the ECG signal collection terminal consists of a ECG signal collection module and a PDA, the module has functions such as the collection,filter and A/D transfer of the ECG signals, and the PDA has the functions such as display of ECG date and transfers the ECG data to the hospital monitoring center. In the center, the doctors diagnose the patients'ECG signals in real-time mode, and supply medical service to the patient. In order to guarantee the correction of the ECG signal during the transmission, we use the socket communication based on the TCP protocol. The monitoring center has the function to display and save the ECG signal, the doctor can use it to find, delete, review and print the ECG signal conveniently.According to the test, the system can correctly transfer the patients'ECG signals to the hospital monitoring center in real-time mode. The system is portable and easy to operate, and it can be used both in first aid and in family tele-monitoring. All in all, the system has values both to the society and the economy.
