Objective To develop a portable lectrocardiograph(ECG) monitor with wireless data communication. Method We use MSP430 microcontroller to control ECG gathering and amplification modules, and send the ECG data to personal digital assistant(PDA) by BCM-03 bluetooth module. Result ECG data gathering and Bluetooth wireless communication with PDA are implemented. The PDA could receive ECG data correctly and perform the functions consisting of ECG wave real-time displaying, storing, diagnosing and remote transmission. Conclusion The monitor meets the design requirements and gets good performrance and stability.
