O objetivo deste artigo é investigar o possível impacto dos sinais de telefones celulares em marca-passos cardíacos implantáveis em elevadores. Isto é conseguido através da realização de simulações numéricas precisas baseadas no método de Domínio de Tempo de Diferença Finita para examinar os campos eletromagnéticos em modelos de elevadores. A fim de examinar as situações realistas e complicadas em que humanos estão presentes no elevador, aplicamos o fantasma humano homogêneo realista e os rádios celulares operando nas bandas de frequência de 800 MHz, 1.5 GHz e 2 GHz. Esses resultados computados da intensidade do campo dentro do elevador são comparados com um determinado nível de referência determinado a partir da distância máxima de interferência obtida experimentalmente de marca-passos cardíacos implantáveis. Isto nos permite realizar uma avaliação quantitativa do risco de EMI para marca-passos por transmissão de rádio celular. Os resultados mostram que para o caso em que estão presentes até 5 usuários de rádio móvel no modelo de elevador utilizado, não há probabilidade de mau funcionamento do marca-passo para as faixas de frequência de 800 MHz, 1.5 GHz e 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.
