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。
