This system was composed of independently developed ECG Signal Acquisition Model, DAQ Signal Acquisition Card, and the LabVIEW Graphics System. Regarding the ECG Signal Acquisition Model, this system uses the TL082 Operational Amplifier to realize the amplification, and uses the Filter Circuits along with the ISO122 to isolate IC. Regarding the ECG oscillogram display and ECG Signal Acquisition, the LabVIEW Graphics System developed by the American company “National Instruments” (NI) was adopted. Also, the LabVIEW system and the DAQ signal acquisition card of the Data Acquisition Package developed by the NI Company was adopted as well.The DAQ signal acquisition card can engage in A/D, DI/O, number counting and time counting applications. At last, it can use the TCP/IP Protocol to send the ECG waveform data by the internet to the computers with remote surveillance monitors. The remote surveillance computers can be installed in the hospital. Professional doctors in the hospital can observe the patient’s ECG waveform data and statistics, and engage in the job of remote care.
