摘要：
The reservoir-wave approach, a wedding of Frank's Windkessel and wave intensity analysis, represents a new alternative to the frequency-domain analysis of aortic input impedance. Re-interpretation of the classical 3-element Windkessel circuit accounts for the diastolic decrease in pressure, obviating the concept of negative flow waves, and also allows estimation of micro-vascular compliance. Finally, it suggests that the minimum in the impedance modulus might be simply due to the addition of reservoir and wave components.
