Computational Analysis of Induced Voltage on Implanted Cardiac Pacemaker's Lead by Mobile Phones

摘要

The proposed paper deals with simulation and analysis of induced electric voltage in pacemaker lead model within the anatomical human body model due to the near-field exposure of dipole antennas covering carrier frequencies of both, GSM and UMTS mobile phone transmission technologies. The research was carried out using electromagnetic modelling based on the Finite Integration method and analysis was performed in terms of computing induced electric field distributions and induced electric voltage near to the pacemaker lead stimulation poles. The main objective was to compare levels of induced voltage on the pacemaker lead stimulation poles for both technologies, depending on the antenna distance from human torso model. The numerical results have shown that closer proximity of antenna than the distance recommended by pacemaker manufacturers could not pose higher pacemaker interference risk. Additionally, the results of estimated induced voltage have revealed that the pacemaker interference risk of recent mobile phone transmission technology is lower compared to older ones.
