Numerical Study of Coupling between Coagulators and Electrodes of Cardiac Pacemakers under Consideration of the Human BodyAbstract
The paper presents a numerical, worst-case study of the coupling between coagulators and cardiac pacemakers under consideration of the human body. For this purpose two special body models have been implemented. With these models whose electrical properties correspond to a weighted average of those of different tissues of the human body the influence of the latter can be taken into account in the computations. Different parameters such as position of the pacemaker and its electrode, coagulation frequency, and coagulation point on the surface of the human body are considered. Based on results of previous investigations simplified approaches to account for the dielectric coating of the coagulator electrode and housing of the pacemaker can be used. The investigation shows, that for the scenario described above, strong peaks occur in the resulting graphs arising form resonance effects on the coagulator cable
