摘要
传统中医认为人体特定的脉搏波频率特性与其脏腑的功能有关。为了研究和阐明脉搏波谐波的产生机理和分布特征,通过对理想脉搏波的离散傅里叶变换进行理论研究,并将真实脉搏波的频谱与理想脉搏波频谱进行比较和分析,验证了真实脉搏波谐波现象存在的合理性。在此基础上,文章提出了一种基于脉搏波谐波特性的更为稳定的心率计算方法。该研究为脉搏波的频域分析奠定了理论基础,对各种类似的准周期信号的分析也具有一定的应用和参考价值。
It is a belief that specific pulse wave frequency characteristics are related to the functions of various organs in traditional Chinese medicine.To investigate and clarify the generation mechanism and distribution characteristics of pulse wave harmonics,theoretical studies are conducted using the discrete Fourier transform of ideal pulse waves.Additionally,a comparison and analysis of the frequency spectrum of real pulse waves and that of ideal pulse waves are conducted to verify the rationality of the existence of real pulse wave harmonics phenomenon.On this basis,a more stable heart rate calculation method based on the characteristics of pulse wave harmonics is proposed.This research establishes a theoretical foundation for the frequency domain analysis of pulse waves,offering significant application and reference value for the analysis of various similar quasi-periodic signals.
