【正文】 t. After the ECG data has been acquired, with the buffer, filter, amplifying and analog to digital conversion circuit, the signal will be conversed to digital and transmitted to the LPC2138 ARM7 based processor. The MCU can process the data and send it out through the Bluetooth chip. This data can be received by the other host and with the softwar e, the ECG waveforms can be displayed. With the using of Bluetooth wireless technology, the ECG data can also be extended to hospital and munity through the network and these play a role in medical resources sharing.Keywords:ECG, Bluetooth
