Abstract
In this paper, the electrocardiograms measurement circuit boards (produced by ZhongYu Technology Company) was used to measure the signal of heartbeat by pasting electrode patches on the limbs. The heartbeat signal is sampled at 500 Hz with data acquisition card (National Instruments) and recorded in the computer. Since the signals recorded in computer would be deteriorated by noise, we prefer to utilize a digital wavelet filter to replace the General IIR digital filter for the superior noise filtering performance. For the extraction of characteristic values, the So and Chan Method is implemented to find Q wave, R wave and S wave. The interval of two R peaks could be measured and calculated to show the heart rate of human body. HRV (heart rate variability) analysis of the human body can then be performed and regarded as the reference for diagnosis of disease.
