Abstract:

The traditional dynamic ECG（ElectroCardioGram）  monitoring device is complex due to many wire connection.The patient‘s body is limited resulting in a sense of restraint and the quality of ECG is  affected.To overcome these drawbacks,we designed a wireless dynamic ECG monitoring device based on ZigBee.The device has the advantages of low power consumption,low cost,light weight,and small size.It is mainly composed of a signal acquisition module and wireless transmission module.The acquired ECG signals are converted to digital signals by the A/D in CC2530,and sent through the wireless module.Via ZigBee wireless transmission,the ECG signals are received by  receiving module and uploaded to PC machine in  serial for real-time display.This study describes the design of the hardware circuit,and gives the flow chart of software program.The device has been tested in the laboratory,and  the real-time ECG waveforms  show that the achieving ECG signals with little distortion can be used for clinic analysis and diagnosis.
