两种滑脉患者与健康妇女指端血管容积脉搏波的谱分析

POWER SPECTRUM ANALYSIS OF THE FINGER PLETHYSMOGRAM IN TWO KINDS OF PATIENTS WITH ABRUPT PULSE AND THE HEALTHY YOUNG WOMEN

本文对部分具有滑脉脉象的患者和健康青年女子的指端血管容积脉搏波进行了功率谱分析比较。见到健康青年女子脉搏波功率谱上的能量基本分布于0～20 Hz频段内。提示血流相对平稳。甲亢患者则在0～200 Hz频段内均有能量分布,其中较高的能量峰位于0～20 Hz段内,此段内能量分布呈早衰现象。提示甲亢患者血管内湍流明显增加,血流平稳度下降。早孕妇的谱分析显示主要能量分布于0～20 Hz段内,此段内能量随频率升高而缓慢下降,不似甲亢患者的早衰。在100 Hz附近多见一个较高的峰。提示早孕妇血流平稳度有所下降,但介介于前两者之间。为用现代科学技术探索脉象成因和研究中医脉学理论提供了依据。

This article deals with the power spectrum analrsis of some healthy young women and some patients with abrupt pulse. It is found that in the healthy young women the spectra show that the most energy basically distributes within the range of 0～20 Hz this suggests that the blood current is relatively smooth. In the hyperthyroid patients it shows that within full range of 0～200 Hz widely distributes the energy and main part of which locates in the range of 0～20 Hz where the distibution of energy shows the phenomenon of early decline. This indicates that there is obvious increase of turbulenoe and decline in blood stability in patients 'vessds. The power spectrum in early pregnant women demonstrates that most part of energy distributes within the range of 0～20 Hz where the energy declines slowly. This is different from that of the hyperthyoid patients. Moreover, nearby 100 Hz there is often seen an obvious peak. These means that the blood stability in eraly pregnant women declines to some extent between above two ses. This article has provided a useful datum for researching the cause of formation of the pulse and studying the theory of pulse condition of the Traditional Chinese Medicine.
