血管壁动态信息的频谱分析

Spectral analysis of vessel wall dynamic information

将功率谱分析的理论运用于血管壁动态信息的分析中,得出了正常人组和病人组压力位移波信号及其速度波信号的典型波形图。其分析结果表明:A信号和D信号的G参数和H参数不但具有统计学意义,而且与人体血管壁的弹性程度成正比,因此该两信号可以作为血管壁弹性程度疾病定量诊断的主要特征量,对早期定量诊断血管性疾病具有一定的临床意义。

In analysis of vessel wall dynamic information,typical oscillogram of PDWVW and speed wave information were gained from normal and vascular patients groups,which were based on analysis theory of power spectrum.The analyzed results showed that the parameter G and H of signal A and D not only had statistical significance,but also were proportional to the elasticity of the vessel wall.So the two signals could be considered as the main characteristic parameters in quantitative diagnosis of the vessel walls elasticity diseases.It may have some clinical significance in quantitative diagnosis of early vascular diseases.
