橈骨動脈脈搏波之頻譜分析

中醫脈學是長久以來應用於中醫臨床診斷的一項實踐方法，歷代文獻及理論經驗的資料都非常豐富。傳統中醫脈學多屬主觀與經驗的描述，欠缺較客觀明確的定量及定性分析，使得中醫脈診在現代醫學中難以被廣泛接受，在臨床研究上亦難以探究發展。雖然目前有多種脈搏波型的擷取儀器被研發出來，以取代傳統手指觸摸橈動脈的診脈方法，不同證型患者的脈搏波型也被客觀描繪出來，但是對於脈搏波形的研究、各項波形參數的分析與臨床意義的探討，和對於不同疾病是否具有臨床指標性的定性和定量分析，一直仍未有顯著的發展。因此，發展脈搏波的客觀化、標準化波形分析法對於提昇中醫脈診的客觀性是非常重要的。本研究擬擷取正常受測者及不同疾病患者撓骨動脈的脈搏波訊號，再以自行撰寫的分析軟體分析脈搏波的波形，定義並計算脈搏波波形不同的參數，以便用統計方法找出不同疾病下波形參數的差異性，以探討脈搏波波形參數在不同疾病的診病價值。

The Power Spectral Analysis of Radial Artery Pulse Waveform

The diagnostic method of pulse palpation has been used in traditional Chinese medicine for thousands of years. There are plenty of archives concerning the description of experience in this diagnostic method and the subjective description about the objective assessment of pulse palpation. There are many manipulations and equipments now to get the waveform of artery pulse instead of the way of traditional palpation on radial artery pulsation. However, The description and calculation of pulse waveform parameters and the unstanding of their clinical meanings need more improvements. The development of standardized pulse waveform analysis is necessary for the improvement of the diagnostic power of pulse palpation in traditional Chinese medicine. This study intends to assess the signals of radial artery pulse wave taken from coronary artery disease patients and control subjects through the plethysmographic monitor and computer programme written with Mathcab software. We will measure and analyze the parameters from the radial artery pulse wave through power-spectral analysis to find the relationship between the parameters defined and the status of the diseases. By means of biostatistics we may be able to find the difference in pulse wave parameters between coronary artery disease patients and control subjects, and the clinical diagnostic value of pulse wave analysis.
