ZHANG Da-wei1, WANG Hai-ke2, ZHANG Bin3. Design of novel wireless 3-lead ECG and research of its processing algorithm[J]. 2013, 32(5): 35-37. DOI: 10.13873/j.1000-97872013.05.019.
A novel design method of wireless 3-lead ECG is presented.ADS1291 with single-channel
24-bit analog front-end for biopotential measurements
STM32L162 based on Cortex-M3 microcontroller
2.4 GHz wireless transceiver nRF24L01 are adopted and respectively used as data acquisition module
data acquisition control and processing module
and wireless communication module of ECG
so as to make it portable
miniaturized
low power consumption.QRS wave detection algorithm which has advantages of low computation and high accuracy based on difference operation method is introduced.A prototype is developed
and experiment verifies the effectiveness of this algorithm.
