摘要： The gate means 73 extracts the partial impedance pulse wave SMIMP(P) from the thorax impedance pulse wave SMIMP detected by the thorax impedance pulse wave detector 64. This is done over an intake period defined as a period starting from a first time T1 after the time when the R wave of the induced electro-cardiac wave is detected to the time when a rising edge of the photoelectric pulse wave SM2 is detected. Then, the heartbeat synchronous information determining means 74 selects a rising edge of the partial impedance pulse wave SMIMP(P) that periodically appears as heartbeat synchronous information IH. Thus, it is possible to accurately determine the heartbeat synchronous information IH. Additionally, since the photoelectric pulse wave SM2 that is detected by the photoelectric pulse wave sensor 40 is largely free of noise it is possible to accurately determine the end of the period for reading the thorax impedance pulse wave SMIMP.

摘要： An arteriosclerosis evaluating apparatus 10 includes an arteriosclerosis evaluating procedure 46 (Steps S7, S8, S9, and S10) that evaluates arteriosclerosis of a living subject, based on a relationship between difference ΔP of internal and external pressure of an artery of the subject in the state in which the pressure difference ΔP is in equilibrium, and amplitude AM of a pulse wave produced from the artery. Therefore, the present apparatus 10 can as easily as possible evaluate the arteriosclerosis of the subject based on a characteristic curve 58 representing the relationship between in-equilibrium pressure difference ΔP and pulse-wave amplitude AM which curve is obtained from a pressing pressure Pc of a cuff 12 wound around a certain portion of the subject, and the pulse wave produced from the artery.
