TABLE 1.

Numerical values of the parameters used in the model of the heart for a cardiac cycle of duration TRR = 0.86 s (corresponding to a heart rate of 70 bpm) in a normal contractility context.

Right atrium Right ventricle Left atrium Left ventricle Tricuspid valve Pulmonary valve Mitral valve Aortic valve
Vdead (ml) 7.0 40.0 3.0 10.0
EA, CC (mmHg.ml–1) 0.06 0.55 0.07 2.75
EB, CC (mmHg.ml–1) 0.07 0.05 0.09 0.10
Tacp, Tvcp (s) 0.15 0.28 0.15 0.28
Tarp, Tvrp (s) 0.15 0.14 0.15 0.14
Aeff,max,CV(cm2) 6.0 5.7 5.1 5.0
leff, CV (cm) 2.0 1.5 2.0 1.0
Kvo, CV (mmHg–1.s–1) 40.0 26.7 26.7 26.7
Kvc, CV (mmHg–1.s–1) 53.3 26.7 53.3 26.7

EA,CC: amplitude of elasticity; EB,CC: baseline value of elasticity; Tvcp, Tacp: duration of the contraction phase for the ventricles and atria, respectively; Tvrp, Tarp: duration of the relaxation phase for the ventricles and atria, respectively; Aeff,max,CV: maximal effective area; leff,CV: effective length; Kvo,CV: rate coefficient for valve opening; Kvc,CV: rate coefficient for valve closing. Numerical values for the cardiac valves and dead volumes are adapted from Mynard and Smolich (2015), while all the other numerical values are adapted from Liang et al. (2009a).
