Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] The method for measuring the pulse wave propagation velocity in the embodiment of the present invention uses Doppler ultrasound to measure and record the arterial pulse wave of a certain part of the human body. Obtain the Doppler ultrasound signal intensity-time map. Measure the time difference Δt between the end point of the main peak descending branch (the moment when the artery stops contracting) and the start point of the dicrotic wave on the time map, and then calculate th...

Abstract

The invention discloses a method and system for measuring pulse wave propagation speed. The method includes: measuring and recording artery pulse wave of a certain part of a human body by using Doppler ultrasound to obtain a Doppler ultrasonic signal strength-time map, measuring a time difference Delta t between a main peak descending branch end and a re-pulse wave start on the time map, calculating an artery total length L from a main artery root to a pulse wave measurement site according to the height H of a testee, pulse wave propagation speed S of the testee on this artery measurement section being equal to a ratio of L to Delta t. The invention provides a novel method of measuring artery pulse wave speed by using the method of measuring pulse wave signals using Doppler ultrasound, in the hope of providing theoretical and technical basis for further clinical application. In addition, the method is simple, operating is convenient, measuring accuracy is higher, and clinical level is partly increased.

Description

technical field [0001] The invention belongs to the technical field of pulse measurement, in particular to a method and system for measuring pulse wave propagation velocity. Background technique [0002] Cardiovascular disease is directly related to the condition of the arteries. Arteriosclerosis is an underlying health problem and a precursor to heart failure, renal syndrome, hardening, and heart attack. Age and systolic blood pressure are the most important factors for increased pulse wave velocity. During aging, arteries calcify and lose their elasticity, so measuring PWV is useful for studying the effects of aging, vascular disease, vasodilation and constriction agents, etc. on arteries. PWV analysis is widely recognized by the European Society of Hypertension as an integral part of the diagnosis and treatment of hypertension. The relationship between pulse wave velocity and cardiovascular related diseases, events and death has been proved by a large number of clinica...
