A Portable ECG Signal Monitor and Analyzer

In recent years, because of the popularity of the computer, more and more people use the computer every day. For people usually forgetting that they need to take a rest during long time of using computer, they made themself in the fatigued state. The fatigued state could be evaluated by electrocardiogram(ECG). This article developed wireless ECG signal measurement and acquisition system. The system integrates ECG signal acquisition and bluetooth modules and the National Instruments LabVIEW software.ECG signal can be analysed to obtain heart rate, heart rate variability (HRV) , respiratory rhythm, the activity of the sympathetic and parasympathetic of autonomic nervous system. This system uses the wireless transmission technology of the Bluetooth to connect with computer. Therefore, the system can record the ECG signal of user while he using the computer or walking free around the computer. National Instruments LabVIEW analyses the physiological signal, displays and stores data in the computer. User can operate the system for monitoring his physiological signal and understanding his health very easily.
