| Summary: | 碩士 === 中原大學 === 醫學工程研究所 === 95 === 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.
