Characteristic impedance (Zo), is characteristic of the properties of the vessel and fluid contained within it. Knowledge of Zo can provide information of the viscous, inertial and elastic components, that is beneficial to the diagnosis of certain cardiovascular diseases. Several approaches have been made to obtain Zo. Among them, the averaging of the input impedance in a certain frequency range is the most frequently used method. Three different methods that have been used to obtain aortic characteristic impedance are compared under normal and vaso-active states in experimental dogs.
