Frequency response of the arterial wall.
The high frequency response of human common iliac arterial segments in vitro was investigated. It was found that at those high frequencies the response resembles that of a second order underdamped system. However, to stimulate the arterial response throughout the frequency range, a higher order model is required. A fifth order system appears to describe the observed behaviour in a satisfactory way between 0.02 and 200 Hz.
