Tujuan kertas kerja ini adalah untuk menyiasat kemungkinan kesan isyarat telefon selular ke atas perentak jantung yang boleh diimplan dalam lif. Ini dicapai dengan menjalankan simulasi berangka yang tepat berdasarkan kaedah Finite-Difference-Time-Domain untuk memeriksa medan elektromagnet dalam model lif. Untuk mengkaji situasi realistik dan rumit di mana manusia berada di dalam lif, kami menggunakan hantu manusia homogen realistik dan radio selular yang beroperasi dalam jalur frekuensi 800 MHz, 1.5 GHz dan 2 GHz. Keputusan pengiraan kekuatan medan di dalam lif ini dibandingkan dengan tahap rujukan tertentu yang ditentukan daripada jarak gangguan maksimum perentak jantung yang boleh diimplan secara eksperimen. Ini membolehkan kami menjalankan penilaian kuantitatif risiko EMI kepada perentak jantung melalui penghantaran radio selular. Keputusan menunjukkan bahawa untuk kes apabila sehingga 5 pengguna radio mudah alih hadir dalam model lif yang digunakan, tiada kemungkinan berlaku pincang fungsi perentak jantung untuk jalur frekuensi 800 MHz, 1.5 GHz dan 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.
