Parameter | Value | Comment |
---|---|---|
Chamber Pressure | q 0  = 100 mmHg | A time-average value on the order of the chamber pressure during ventricular systole |
Pericardial Pressure | q 1  = 2 mmHg | |
Extracellular Shear Modulus | G = 104 Pa | |
Ratio of Elastic Moduli | μ/G = 3 | Based on Ohayan, et al. Implies Δ = Πin Eqs. 27 & 28 |
Active Tension | T 0 = 100 N/m 2 | A time-average value on the order of systole for isolated myocytes (Chen & Varghese 2010) |
Radius of Inner Chamber | a = 3.14 cm | Implies an inner chamber volume similar to the human left ventricle |
Radius of Spherical Heart | b = 4.24 cm | Implies a wall thickness similar to the human left ventricle |
Estimate of Coupling Parameter | K ≳ 109 − 1010 N/m 3 | Based on experimental data of 5 to 6 mm displacement in canines, Eqs. 29 & 31, and Figure 3 |
