  • Abstract By the improvement of the environment, medical care and science, the daily physiological signal of the patients can be observed and recorded by the infirmarian in an un-disturbed place. Hence, the wireless tool without distance limit is very important. The thesis presents the real-time wireless ECG device which achieves the goal of faraway observation and record and has different tests and analysis.
    The measurement of the ECG signal has properties of simple measurement, non-invasive, plenty data and easier analysis. Hence, the ECG is an important acknowledge in the cardiacal branch like arrhythmia, ventricular hypertrophy and myocardial infarction. Basis on the doctor experience, those cardiopathy diagnosed from the characteristic of the ECG wave of the time domain. The thesis uses the wireless ECG device to measure ECG signal or samples from MIT-BIH and use the algorithm of the system identification to build the system model of the ECG signal and compare the difference of the system model of the normal man and the patient. The proposed idea wish helping doctor to diagnose cardiopathy.
