BAROREFLEX VASCULAR SYMPATHETIC NERVOUS ACTIVITY DETECTION DEVICE, BAROREFLEX VASCULAR SYMPATHETIC NERVOUS ACTIVITY DETECTION PROGRAM, AND BAROREFLEX VASCULAR SYMPATHETIC NERVOUS ACTIVITY DETECTION METHOD

摘要

[Problem] To provide a baroreflex vascular sympathetic nervous activity detection device, baroreflex vascular sympathetic nervous activity detection program, and baroreflex vascular sympathetic nervous activity detection method making it possible to detect baroreflex vascular sympathetic nervous activity, which is sympathetic nervous activity of the blood vessels associated with baroreflex function, in a simple and non-invasive manner. [Solution] A baroreflex vascular sympathetic nervous activity detection device 1 for detecting baroreflex vascular sympathetic nervous activity, which is sympathetic nervous activity of the blood vessels associated with baroreflex function, on the basis of pulse wave data on a body artery and a beat interval corresponding to the pulse wave data, wherein the baroreflex vascular sympathetic nervous activity detection device includes a VBRSA series detection unit 44 for detecting, as a baroreflex vascular sympathetic nervous activity series indicative of baroreflex vascular sympathetic nervous activity, a series where, from among series where the beat interval increases or decreases for n (n being a natural number 3 or higher) consecutive beats, a correlation coefficient for the beat interval and pulse wave data is greater than an arbitrary positive threshold value up to the (n-1)-th beat and the correlation coefficient at the n-th beat is the threshold value or below.
