Arteriosclerosis is one of the early characteristics of cardiovascular diseases, and pulse wave velocity (PWV) has the ability to reflect on arterial elasticity, so the accurate measurement of PWV can be of benefits for the prevention and treatment of cardiovascular diseases. There are two methods based on volume pulse waveform and based on pressure pulse waveform for taking the measurement of PWV. The precision of detection depends mainly on choosing the recording sites of PWV. There are several methods to choose the recording sites of PWV. We can get it by tangent and by low-water mark or culmination. We also can choose the recording sites of PWV by getting the point where the greatest slope stands. The advantages and limitations of the existing methods are analyzed in this article, and the relative research orientation in the world is addressed. Lastly a scheme for improving the detection method is presented.
动脉硬化是心血管疾病的早期特征之一，脉搏波速度（PWV）能够反映动脉弹性，因此准确测量PWV有助于心血管疾病的防治。测量PWV有基于容积脉搏波形和基于压力脉搏波形两种方法。检测精度主要取决于PWV记录部位的选择。选择PWV记录部位有多种方法。可以通过切线法、低水印法或峰值法获取。也可以通过获取最大斜率点来选择PWV记录部位。本文分析了现有方法的优缺点，并探讨了国际上的相关研究方向。最后提出了一种改进检测方法的方案。
