The source of disturbance is a sinusoidal electrical signal with amplitude of 10 V; the frequency ranges studied corre- spond to the frequencies of the electrical distribution network (50/60 Hz) and to the frequencies of domestic applications (10/25KHz). The numerical simula- tions were carried out according to two methods, the first based on the finite el- ement method using the Comsol multiphysics software, the second is based on the impedance method. The results obtained by the two methods are in good agreement, and this will allow us to calculate the voltage induced between the ends of the stimulator. These results allowed us to validate the proposed model.

They live in an electromagnetic environment (EMF), of natural but also artificial origin, and the latter is the result of the increased use of electrical energy, necessary to operate surveillance devices, household appliances, and communications...etc. Also medical equipment used in the diagnosis of diseases such as magnetic resonance imaging (MRI) and therapeutic applications in psychiatry and neurology such as transuranic magnetic stimulation (TMS) [17] and electrical stimulation therapy (EST) [2]. This raises ques- tions about the possible effects of exposure to these fields on human health and on the proper functioning of the devices (ICEDs) [21], [22]. The latter proved effective in reducing mortality in patients at high risk of developing ventricular arrhythmias [3]. These two questions have been the subject of several studies over the last decades, in vivo and in vitro. A. Hedjeidj et al in 2002 showed that the exposure of certain PCs to NDEs under specific conditions caused their dysfunction [4]. J Silny et al, in 2014 they showed after the exposure of 110 patients (worn ICDs of 1,2, and 3 chamber) to strong electric and magnetic fields of 50 Hz ranging up to 30kv / m, and 2.55 mT in iJOE ‒ Vol. 18, No. 01, 2022 65
