ABSTRACT
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.
