Arteriosclerosis has a huge influence on human's health. Currently the diagnosis of arteriosclerosis is based on invasive cardiac catheter measurement, but this method could cause subject's great inconvenience and might be dangerous. In this regard, this paper proposes a non-invasive pulse characteristic points locating system for arteriosclerotic degree examination. The pulse characteristic points we use include pacemaker, percussion wave peak, dicrotic notch and dicrotic wave peak. From the pulse characteristic points, we can calculate the arteriosclerotic degree examination parameters, such as pulse wave velocity, stiffness index and reflection index, etc. Those parameters can be used for diagnosing the degree of arteriosclerosis.
动脉硬化对於人体健康有极大的影响,然而目前动脉硬化的诊断主要在於侵入式的心导管量测,容易造成受测者的诸多不便及危险性;有鉴於此,本论文系设计一应用於动脉硬化程度检测之脉波特徵点定位系统,如:起搏点、主波峰顶点、重搏切迹与重搏波顶点等,经由准确的脉波特徵点定位计算出脉波传导速率、硬化指数与反弹指数等动脉硬化程度检测参数,透过这些数据,可提供医师在诊断动脉硬化程度上的辅助。

This system mainly contains the front-end pulse interception and back-end software analysis. In the first part, we used a non-invasive infrared measurement method based on the dual channel simultaneous measurement technique. We measured the photo-plethysmograph from the subject's fingers and toes simultaneously, then used an analog circuit and central control unit to process the signals. Finally, the digital volume pulse data is processed by a personal computer. Because the characteristic points of digital volume pulse always occur in sharp variations, this paper proposes two algorithms to solve this problem. First, we find the pacemaker and percussion wave peak from transient slope variation, and then locate the dicrotic notch and dicrotic wave peak by using the wavelet transformation algorithm. When we analyze the data, we use the Visual Basic graphical user interface, which together with the Matlab is the core of the system.
本系统主要包含前端脉波撷取及后端软体分析两部分,其中前端脉波撷取部份是以非侵入式的红外线量测方式,双通道同步量测受测者手指与脚趾的光容积变化描记图,同时将此讯号经类比处理电路及中央控制单元输出成为数位容积波,再传送至个人电脑中;而在后端软体分析部份,因数位容积波之特徵点皆出现於波形中急剧变化的部份,故本论文以瞬间斜率变化量来定位脉波讯号中的起搏点及主波峰顶点,并利用小波转换演算法(wavelet transformation algorithm)来分析重搏切迹与重搏波顶点;程式撰写主要以Matlab为核心,结合Visual Basic的图形化使用者操作介面,增加系统与使用者间的亲和力。
