摘　　要：目的探讨从脉搏波中提取特征点,使人体的生理病理信息作为临床诊断和治疗依据的可行性。方法采用阈值法提取出脉搏波形信号中主波和重搏波的两个基本特征点。结果所使用的阈值法较为准确地实现了对脉搏波形中的两个特征点进行提取的功能。结论阈值法能够较好地提取出脉搏波形图中的两项主要特征点,不影响原信号的其他特性,方法简单,易于实现,适合应用于脉搏波形的简易分析和处理。Objective To investigate the feasibility of physiological information,diagnosis and treatment by picking characteristic points from the pulse wave. Methods The threshold method was applied to pick up two characteristic points of main wave and dicrotic wave. Results This method precisely realized function of two characteristic points picked. Conclusion Two characteristic points of the pulse wave can be picked well through the threshold method and the process cannot influence the original signal.The method is easy to apply to analyzing and processing pulse wave.
