Key result
The improved three-element Windkessel model with a complex capacitance accurately captured the fundamental-frequency time lag, significantly reducing the modeling error of the pulse wave in large arteries.
An improved complex Windkessel model reduces modeling errors in simulating pulse wave propagation in arterial trees compared to standard models.

Enhances large-artery pulse wave modeling fidelity; leaves open clinical translation pending prospective validation.
Du et al. (2015) studied Blood flow modeling in arterial trees. Complex Windkessel model (CWK) vs. Standard three-element Windkessel model (WK) was evaluated on Modeling error of the pulse wave (blood pressure and flow rate). The improved three-element Windkessel model with a complex capacitance accurately captured the fundamental-frequency time lag, significantly reducing the modeling error of the pulse wave in large arteries.
