W4P is an alternative four-element windkessel formulation, derived from the three-element windkessel by connecting an inductance L in parallel with a low-resistance term, Rc, which is given the meaning of aortic characteristic impedance. W4S is an alternative four-element windkessel formulation, derived from the three-element windkessel by connecting an inductance L in series with a low-resistance term, Rc, which is given the meaning of aortic characteristic impedance. IVW is an alternative four-element windkessel formulation, derived from the three-element windkessel by connecting an inductance L in series with a viscoelastic windkessel, where a Voigt cell (a resistance, Rd, in series with compliance, C) accounts for viscoelastic properties of vessel wall motion.
