Abstract: 

Pulse wave velocity is often used as an indicator clinically for diagnosis of cardiovascular diseases. This assumption is well grounded in the physics of pulsatile flow of an incompressible fluid where it is fully established that a pulse wave travels faster in a tube of stiffer wall, the wave speed becoming infinite in the mathematical limit of a rigid wall.
In this paper we point out that pulse wave velocity in a stiffer tube is strictly valid only when the wall is free from outside constraints, which is used as the outer boundary condition (tethering: the degree to which the vessel wall is surrounded by tissue). In this paper, using the equations of blood fluid and vessel walls and using analytical solutions and the use of tethering as outer boundary conditions pulse wave velocity is investigated. In previous research pulse wave velocity has been obtained just for the tethering zero and one, but in this study pulse wave velocity is investigated for different degrees of tethering, and for three different material walls: viscoelastic, elastic and stiff. In this research pulse wave velocity for different degrees of tethering and different material wall are determined. These results can be of considerable help in the use of pulse wave velocity as an clinical index to predict arterial stiffness.
