Le but de cet article est d'étudier l'impact possible des signaux des téléphones portables sur les stimulateurs cardiaques implantables dans les ascenseurs. Ceci est réalisé en effectuant des simulations numériques précises basées sur la méthode des différences finies dans le domaine temporel pour examiner les champs électromagnétiques dans les modèles d'ascenseur. Afin d'examiner les situations réalistes et complexes dans lesquelles des humains sont présents dans l'ascenseur, nous appliquons des radios fantômes et cellulaires humaines homogènes et réalistes fonctionnant dans les bandes de fréquences 800 MHz, 1.5 GHz et 2 GHz. Ces résultats calculés de l'intensité du champ à l'intérieur de l'ascenseur sont comparés à un certain niveau de référence déterminé à partir de la distance d'interférence maximale obtenue expérimentalement des stimulateurs cardiaques implantables. Cela nous permet de réaliser une évaluation quantitative du risque EMI pour les stimulateurs cardiaques par transmission radio cellulaire. Les résultats montrent que dans le cas où jusqu'à 5 utilisateurs de radio mobile sont présents dans le modèle d'ascenseur utilisé, il n'y a aucune probabilité de dysfonctionnement du stimulateur cardiaque pour les bandes de fréquences 800 MHz, 1.5 GHz et 2 GHz.

Abstract: The purpose of this paper is to investigate the possible impact of cellular phones' signals on implantable cardiac pacemakers in elevators. This is achieved by carrying out precise numerical simulations based on the Finite-Difference-Time-Domain method to examine the electromagnetic fields in elevator models. In order to examine the realistic and complicated situations where humans are present in the elevator, we apply the realistic homogeneous human phantom and cellular radios operating in the frequency bands 800 MHz, 1.5 GHz and 2 GHz. These computed results of field strength inside the elevator are compared with a certain reference level determined from the experimentally obtained maximum interference distance of implantable cardiac pacemakers. This enables us to carry out a quantitative evaluation of the EMI risk to pacemakers by cellular radio transmission. The results show that for the case when up to 5 mobile radio users are present in the elevator model used, there is no likelihood of pacemaker malfunction for the frequency bands 800 MHz, 1.5 GHz and 2 GHz.
