BLOOD PRESSURE ANALYZER, BLOOD PRESSURE MEASUREMENT DEVICE, BLOOD PRESSURE ANALYSIS METHOD AND BLOOD PRESSURE ANALYSIS PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a blood pressure analyzer, a blood pressure measurement device, a blood pressure analysis method and a blood pressure analysis program capable of correctly determining a factor of blood pressure change which is useful in diagnosis.SOLUTION: A blood pressure analyzer 2 determines whether or not first blood pressure information of an optional beat out of blood pressure information for plural beats recorded in a recording medium 14 for recording blood pressure information for plural beats which are calculated for one beat unit based on a pulse wave detected from a wrist of a subject, and wrist motion information detected by an acceleration sensor 12 in a detection period of the pulse wave which is a calculation source of the blood pressure information for plural beats, is changed by a threshold value TH 1 or more, to second blood pressure information of a beat which is previous to the optional beat, and if the determination result is YES, determines whether a factor of blood pressure change is a motion of a wrist or other than the motion of the wrist, based on detection information of the acceleration sensor detected in the detection period of the pulse wave which is the calculation source of the first blood pressure information, then, associates the determination result and the first blood pressure information and records them in a recording medium 23.SELECTED DRAWING: Figure 4
