摘要： PROBLEM TO BE SOLVED: To easily correct a phase deviation between a stress signal and a distortion signal with a simple configuration without performing determination after comparison with a catheter whose phase characteristic is previously known. SOLUTION: A blood vessel viscoelasticity measuring instrument 1 includes: a calculating part 9 for correcting the phase deviation between the stress signal and the distortion signal, based on a shift time with the maximum determination coefficient, which expresses a multiple correlation coefficient between an estimation stress signal, obtained by performing regression calculation, based on the distortion signal expressing the distortion of a blood vessel along the radial direction of a blood vessel wall, and the stress signal, expressing the stress of the blood vessel along the radial direction of the blood vessel wall; an instrument control part 10; and a timing control part 11.

摘要： PROBLEM TO BE SOLVED: To provide a blood vessel state measuring instrument, a control program and a recording medium surely evaluating the vascular lesion such as the arteriosclerosis and the like. SOLUTION: This blood vessel state measuring instrument is provided with an electrocardiograph 2 for measuring and outputting an electrocardiogram of a subject 1. This instrument is further provided with a plethysmographic apparatus 3 for measuring a change in the outer circumferential length of a front arm 1a, or a part including the artery 1b in the subject 1. This instrument is also provided with a hemodynamometer 4 for detecting the blood pressure value in the artery 1b. This instrument has a computer part 5 for measuring the blood vessel state of the artery 1b by calculating at least one of the viscosity and rigidity of the artery 1b based on the electrocardiogram, the change in the outer circumferential length and the blood pressure value.
