摘要：

Clinical results in cardiac radiofrequency catheter ablation suggest that lesion depth and geometry depend on the used catheter electrode and its working angle related to the myocardium. Aim was therefore, to quantify lesion formation during conventional and cooled radiofrequency ablations by a simplified model. Simulating 60s lasting applications, propagation of the lesion geometry was studied using the COMSOL Multiphysics software. Results were confirmed by experienced electrophysiologists.
