摘要

高血壓是現代社會中最普遍的一項疾病，為我國國民疾病之ㄧ。目前西醫在高血壓疾病的治療上，大都是利用藥物來強制性降低病人的血壓。這種做法只是治標不治本，只是透過藥物來將血壓降低，而無法找出真正引起高血壓疾病的病因。因此，本研究之目的為利用中醫傳統理論，透過脈波和良導絡分析方式，找出高血壓病患中，脈波和良導絡的高血壓特徵參數，並探討此兩種參數之相關性；此外，更利用找出的高血壓特徵參數建構一高血壓辨析系統。
實驗方面，本研究共蒐集30名高血壓病患和45名正常人，量測其左手橈動脈脈波和12經絡良導絡代表測定點的皮膚電阻值，然後利用使用Matlab軟體所撰寫的特徵參數擷取介面，自動擷取所需要的脈波特徵參數(∠U, ∠P1, ∠P2, ∠P)和良導絡特徵參數(12經絡電阻值和左右12經絡電阻差值)，再透過t-test分析找出高血壓病患和正常人間的差異性以及脈波和良導絡兩種特徵參數間的相關性。系統方面，我們從蒐集來的75名受測者中，選取30名高血壓病患和30名正常人的資料來建立系統的決策樹規則，其中44名受測者資料(22名高血壓病患和22名正常人)被用來建立決策樹規則，之後再利用剩下的16名受測者資料(8名高血壓病患和8名正常人)來測試規則的準確率，最後再透過Matlab軟體撰寫一高血壓辨析介面，搭配特徵參數的自動擷取介面以及脈波和良導絡的檢測儀器，構成一高血壓辨析系統。
研究結果顯示，高血壓病患在脈波特徵參數方面會出現∠P明顯大於正常人或是∠P不明顯大於正常人但∠U明顯小於正常人的現象發生；而在良導絡部份，高血壓病患在左右側的心包經、心經、小腸經、三焦經、肝經、腎經、膽經和右側的膀胱經等經絡的電阻值會明顯高於正常人，並且在心包經、三焦經、肝經、腎經、膀胱經和膽經等經絡出現左右經絡不平衡的現象。此外，也發現高血壓病患中電阻值較高或是左右不平衡的經絡愈多的人，其脈波的主波(P波)角度也愈大。系統準確率方面，則發現使用脈波和良導絡兩種參數综合分析的準確率可以達到81.25%左右，較單獨使用脈波的準確率68.75%或單獨使用良導絡參數的準確率71.88%來得高。

Hypertension is the most general disease in modern society and is a national disease of our country. Now the treatment of hypertension is mostly to utilize medicines to reduce the patient's blood pressure mandatorily in western medicine. It tackles a problem on the surface, not at the root. It is unable to find out the real cause of disease of hypertension. Therefore the purpose of this research was to find out the characteristic parameters of hypertension using analytical method of the pulse wave and Ryodoraku. Also it was to analyze the relationship between the characteristic parameters of pulse wave and Ryodoraku. Besides, the research was to built a system of differentiation and analysis of hypertension.
In the research, forty-five healthy adults without cardiovascular disease and thirty hypertension patients were recruited for the experiment. The characteristic parameters of pulse wave were ∠U, ∠P1, ∠P2, ∠P and the characteristic parameters of Ryodoraku were the resistant values of 12 meridians and the difference of resistance between the left 12 meridians and the right 12 meridians. The study used t-test to find the difference between healthy adults and hypertension patients and to analyse the dependence between the characteristic parameters of pulse wave and Ryodoraku. In addition, it set up the rules of differentiation and analysis of hypertension by characteristic parameters of hypertension using decision tree and built a system of differentiation and analysis of hypertension using Matlab.
The result of this research showed that hypertension patients may have one of following two phenomena: ∠P of hypertension patients was obviously larger than that of healthy adults or ∠P of hypertension patients was not obviously bigger than the healthy adults but that ∠U of hypertension patients was obviously smaller than the healthy adults. On the characteristic parameters of Ryodoraku, the resistant values of meridians (Right Meridian: Pericardium, Heart, Small Intestine, San Jiao, Liver, Kidney, Bladder and Gall Bladder; Left Meridian: Pericardium, Heart, Small Intestine, San Jiao, Liver, Kidney and Gall Bladder) of hypertension patients were significantly higher than that of healthy adults and the left meridians and the right meridians of hypertension patients were unbalance (meridian of Pericardium, San Jiao, Liver, Kidney, Bladder and Gall Bladder). Furthermore, it was also found that the angle of P wave would be relatively large when hypertension patients had more problem with meridians. On accuracy of the system, we found that it approximately had 81.25% by combined analysis of characteristic parameters of pulse and Ryodoraku. It was higher than the rate of accuracy by analysis of characteristic parameters of pulse or Ryodoraku alone.
