| Abstract: | This paper introduces the design of a portable ECG monitor based on Bluetooth. The system adopted MSP430FG439 micro-controller as core control unit, and used high-accuracy instrumentation amplifier INA321 as pre-amplifier and OPA4336 as post-amplifier. The data was sent to computer by GC-02 Bluetooth module. The design of Right-Leg Drive Circuit can restrain the common-mode interfere efficiently. The software for displaying the 3-lead ECG graph and the heart-rate was written in C on the MFC platform. The system can monitor ECG signal real-time. In addition, the system has the advantage of high CMRR,low power and low cost. |
