摘要
光电容积脉搏波表征了血管弹性功能。本文介绍用快速富叶变换研究其频域特性,得出正常型和硬化型脉搏波在频谱上的反映特征。为临床诊断提供了更为准确的判断依据。文中绘出了实验测试结果。
In this paper the properties of photoelectric plethysmography in the frequency domain are discussed with the aid of FFT algorithm,and the characteristics of the frequency spectra for normal mode and sclerotic made photoelectric plethysmographies are obtained. It will be very useful for the clinical diagnoses.
