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.
