The hardening characteristic spectrum analysis of vascular wall elasticity noninvasive dynamic information
In the analysis of vascular wall dynamic information, typical oscillogram of pressure displacement wave of vascular wall (PDWVW) and speed wave information were gained from normal and patient 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 vascular walls elasticity diseases. It may have some clinical significance in quantitative diagnosis of early vascular diseases.
