Nerve pressure baroreflex sensitivity measuring device, nerve pressure baroreflex sensitivity measuring program and nerve pressure baroreflex sensitivity measuring method

摘要

To provide a neuro-baroreflex sensitivity measurement capable of simply and objectively measuring a baroreflex sensitivity which does not depend on a hardness of a blood vessel without using pulsation change of a blood vessel diameter or a carotid artery pulse diameter Apparatus, a neural pressure re fl ection sensitivity measuring program, and a nerve pressure baroreflex sensitivity measuring method.A pulse wave data acquisition unit that acquires pulse wave data of an artery; a normalized pulse wave volume calculation unit that calculates a normalized pulse wave volume based on pulse wave data; A beat interval acquisition unit 43 that acquires a beat interval, a pressure reflection series detection unit 44 that detects a pressure reflection series in which both the normalized pulse wave volume and the beat interval successively increase or decreases by three or more beats, a pressure reflection series detection unit 44 that detects pressure reflection series And a nerve pressure baroreflex sensitivity calculating unit 45 for calculating the slope of the regression line showing the correlation between the normalized pulse wave volume and the beat interval as the neural pressure reflection sensitivity which is an indicator of neural baroreflex function.
