Mini Electrodes on Ablation Catheters: Valuable Addition or Redundant Information?—Insights from a Computational Study

Table 1

Overview of intracellular and extracellular conductivities and CV for several temperature ranges. The intracellular conductivity in the border zones was exponential and is given as the range of values in this zone. We assumed a specific membrane capacity of 0.1 μF/cm2 and a surface to volume ratio of 100 mm−1 for the myocardium [25].
