Architectural parameters. Values were obtained by non-linear regression of frequency distribution of data from left ventricle (LV), septum (S), and right ventricle (RV) of six mouse hearts (see Figure 3). λ: length constant of one-phase exponential decay. μ and σ: mean and standard deviation of Gaussian distribution. τ: tortuosity constant of one-phase exponential decay.
