  • 摘要: 人體脈搏波速度(PWV)被認(rèn)為是體現(xiàn)心腦血管健康和血管壁彈性變化的重要因素之一。醫(yī)學(xué)上對(duì)脈搏波速的研究也變得越來(lái)越熱，許多諸如糖尿病、高血壓、冠心病、動(dòng)脈硬化等疾病也都與之有密切關(guān)系。因此，對(duì)脈搏波速度(PWV)的檢測(cè)具有重要的、特殊的意義。該文主要從信號(hào)提取和信號(hào)分析方面入手研究脈搏波，利用標(biāo)準(zhǔn)時(shí)鐘信號(hào)插入所提取的肱動(dòng)脈與橈動(dòng)脈信號(hào)之間以及多點(diǎn)脈搏波信號(hào)相位差之間取平均值的雙模算法，從而更精確地計(jì)算出PWV，并且其求解的PWV標(biāo)準(zhǔn)差為0.06~0.12。該文所使用的雙模算法在實(shí)時(shí)性、測(cè)量精度和穩(wěn)定性方面，優(yōu)于傳統(tǒng)的PWV測(cè)量方法，可應(yīng)用于脈搏波相關(guān)的醫(yī)學(xué)研究和實(shí)驗(yàn)中。
    Abstract: Human Pulse Wave Velocity (PWV) is considered to be one of the important factors that reflects the cardiovascular and cerebrovascular health and the elasticity change of vascular wall. The research of medical pulse wave velocity becomes increasingly hot, such as diabetes, high blood pressure, coronary heart disease, atherosclerosis and other diseases are also closely related. Therefore, the detection of PWV has important and special significance. This paper focuses on signal extraction and signal analysis to study the pulse wave, using the standard clock signal to insert the signal extracted between the brachial artery and radial artery and the dual-mode algorithm of the average among the phase difference of multi-point pulse wave signal, then the PWV is accurately calculated, and its standard deviation is between 0.06 and 0.12. The dual-mode algorithm is superior to the traditional PWV measurement method in real-time, measurement accuracy and stability. It can be used in pulse wave medical research and experiments.
