摘要：

Due to the difficulty of electromagnetic interference (EMI) measurement in an actual pacemaker use situation, the recommendations for the management of health risks of implanted pacemaker users from portable telephones have been developed, based mainly on an in-vitro measuring system with a cuboid liquid phantom simulating a homogeneous human body. The validity of such a highly simplified human body model, however, has never been carefully examined. In this paper, with the application of our previously proposed numerical method for the EMI evaluation of pacemakers by portable telephones, we first confirmed Irnich's finding that the maximum interference distance increases with the third root of the antenna transmitting power for a homogeneous cuboid torso model in order to show the validity of our modeling. We then investigated whether the finding holds true for an actual human body using an anatomically based human model, and confirmed the usefulness of the simple cuboid model in the EMI evaluation for cardiac pacemakers.
