  The objectives of this study are to model the endocardiac radiofrequency (RF)
ablation procedure and to employ the Hyperbolic Bioheat Equation (HBE), which
takes the thermal wave behaviour into account, comparing the results with those
obtained using the common Pennes Bioheat Equation (BE) method. A complex model
is created to cover particular endocardiac physical and geometry environment.
Finite Element Method (FEM) is adopted to study the model with both BE and HBE
methods. Different convection coefficients and voltages are applied to simulate
different conditions. Lesion size, max temperature and specified position
temperature are selected as criteria to evaluate the simulated results. The
study found that during ablation, the lesion size difference ratio can reach
20% in some periods. The difference is obvious and cannot be neglected.
