${\sigma }_l=$ conductivity along the direction of myocardial fiber, ${\sigma }_t=$ conductivity perpendicular to the direction of myocardial fiber, $\overline{\sigma }=$ average value of ${\sigma }_l$ and ${\sigma }_t$, DFT $=$ defibrillation voltage thresholds, POD $=$ Percentage of difference between the DFT of isotropic conductivity and the DFT of anisotropic conductivity. The units of ${\sigma }_l$, ${\sigma }_t$ and $\overline{\sigma }$ are S/m. The information obtained directly from different literatures is 1–4, 6 columns of the table. DFT is obtained by simulation.
