| Abstract: | The recently proposed energy-balance method for estimating the series resistance of the three-element Windkessel model is
reformulated in the frequency domain. New mathematical expressions are analytically derived, involving Fourier harmonics of
pulsatile arterial pressure and flow. It is shown that the series resistance of the arterial three-element Windkessel model
can be expressed as a weighted sum of the arterial input impedance moduli. |
