Abstract: An object of the present invention is to provide a pulse wave analyzing software and a pulse wave analyzing apparatus each of which can extract, from a pulse wave, more information related to an artery. When a series of formulas developed by the Inventor are applied to pulse wave data, electrocardiogram data, and phonocardiogram data that are measured as time elapses, new parameters related to an artery (e.g., a volume elasticity modulus (Km), a Young's modulus (EA), etc.) can be calculated. These parameters can be used to evaluate functions of a living being in a non-invasive, accurate, easy, and quick fashion.
