Morphological analysis of the pulse wave of central blood pressure signal is commonly used for the study of cardiac and vascular properties, but very few attempts were performed for analyzing the peripheral pulse wave of blood flow. In this work, we analyzed this waveform using classical methods, based on the application of FFT, followed by principal components analysis, for assessing the properties of the blood flow. As a sample problem, we evaluated the capability of the proposed method of assessing the alterations correlated with the aging of the vascular system. Results show a good discrimination between the different age groups, confirming the validity of the approach.
中心血压信号脉搏波的形态学分析常用于心脏和血管特性的研究，但对分析外周血流脉搏波的尝试却很少。在这项工作中，我们基于快速傅里叶变换（FFT）的应用，采用经典方法对该波形进行分析，随后进行主成分分析，以评估血流特性。作为一个示例问题，我们评估了所提出方法评估与血管系统老化相关变化的能力。结果显示不同年龄组之间有良好的区分度，证实了该方法的有效性。
