The tissue hydrostatic pressures functions. The intracellular (top plot) and extracellular (bottom plot) pressure functions are plotted as a function of the extracellular shear modulus G divided by the spring coupling constant K. Active tension is T 0 = 100 N/m 2 is maintained (Chen & Varghese 2010) and the ratio of the intracellular Young’s modulus μ to the extracellular shear modulus is given as μ/G = 3. The pressure curves follow a general relation (A + BG/K)/(C + DG/K), where A, B, C, and D and are constants; as shown, this relation holds for various depths within the heart wall. At the boundaries, intracellular pressure is zero and extracellular pressure is equal to the chamber and pericardial pressures for all values of K.
