Abstract: We investigated how parameters describing the heart and the arterial system contribute to the systolic and diastolic pressures (Ps and Pd, respectively) and stroke volume (SV). We have described the heart by the varying-elastance model with six parameters and the systemic arterial tree by the three-element windkessel model, leading to a total of nine parameters. Application of dimensional analysis led to a total of six dimensionless parameters describing dimensionless Ps and Pd, i.e., pressures with respect to… Show more

“…The Windkessel has also been used in theoretical analyses where a heart model and arterial system (Windkessel model) are coupled and the contribution of changes in parameters to blood pressure are calculated [10,61]. An example of such an analysis is shown in Table 2 [61].…”

“…Fixed values are assumed for L (0.005 mm Hg·s 2 /mL) and Z 0 (0.033 mm Hg·s/mL), [15] 2 parameters that have been shown to have limited impact on pressure and flow. [14] It is further assumed that total arterial compliance does not differ between the subgroups, being 1.15 mL/mm Hg, a value that we have found in another study for age-matched hypertensive patients. [15] The impact of total arterial compliance on hemodynamics will be further assessed.…”

“…All cardiac parameters used are obtained from Devlin et al [13] and are directly implemented in our model. Concerning the arterial model parameters, we assumed constant reference values for Z 0 and L, parameters that have a negligible impact on blood pressure and cardiac output in their physiological range, [14] [19] as well as a constant compliance. We have done a coarse scan of the R-R L,ao parameter space for the solution that yields the closest match between measured and predicted cardiac output, systolic pressure, and regurgitation index.…”
