英文摘要	Using traditional pulse analysis method could bring serious influence on the accuracy and reliability of pulse signal feature detection. In order to overcome the shortcoming of the traditional threshold algorithm in peak detection of pulse signal, also to avoid the risk caused by the interference segment of pulse signal on signal analysis, a dynamic threshold method was presented to extract the peak of pulse wave. The symbolic aggregate approximation algorithm was timely used according to the difference and amplitude threshold to detect interference segment in the process. The pulse signals collected in the experiment of video display terminal fatigue were analyzed by this method. The results show that the proposed method can accurately extract the pulse peak and the position. It is obviously superior to the traditional method.
