Abstract
An arteriosclerosis diagnostic device according to various embodiments is a simple device, resistant to an external factor, such as an error resulting from a skin surface, and capable of measuring the degree of hardness of an artery. The arteriosclerosis diagnostic device detects a heart sound and a pulse wave at least one location of a living body, the pulse wave propagating through an artery in relation to the heart sound, converts detected signals thereof into respective frequency signals, specifies the peak frequency of each of the frequency signals, and determines the degree of arteriosclerosis on the basis of the difference between the peak frequency of the heart sound and the peak frequency of the pulse wave. Accordingly, the degree of arteriosclerosis can be determined by comparison between the frequency signals.
