“…The sensitivity level of each channel must be set lower than the value of the sensed signal and it is usually set to half because of the prevention of undersensing. Due to the setting, the atrial channel is more sensitive to external interference than the ventricular one [2,5].…”

“…Inhibition of cardiostimulation may occur and it can cause asystole in pacemaker dependent patients. In the case of ICDs, there is a risk of an inadequate antitachyarrhythmia high voltage therapy (defibrillation shock) [2]. The presence of signals of electromagnetic interference can also initiate temporary changes in the programming of CIEDs.…”

The study deals with the interdisciplinary topic of the electromagnetic compatibility of the cardiac implantable electronic devices that are used in patients with a defect of heart conduction system. We are focusing on the detection of disturbing signals on electrodes of cardiostimulation device and its interpretation. The detection of electromagnetic interference (EMI) is related to electrode choice, device placement, its configuration and programming. The aim of the study is the analysis of the pacemaker response in the presence of an external source of the disturbance fields. We point to possible risks of its interaction and discuss mechanisms that can influence the pacemaker sensitivity to EMI. Due to improper signal detection, the device programming changes can occur. We present an experiment of the exposure of the cardiostimulation system to a low-frequency harmonic interference signals and finally we analyse similar clinical episode and discuss proper functioning of the pacemaker.

When the popular means of transportation—high-speed trains meet the increasing rate of pacemaker implantation year by year, the research on the magnetic field environment on the health of pacemaker wearers in the carriage becomes an urgent problem. In this work, models of an electric multiple unit carriage with a pantograph as well as passengers with pacemakers were built by using COMSOL Multiphysics software. The B, Ein and Jin of human heart and other tissues, and the induced voltage (Vin) at the pacemaker electrode were calculated under the pantograph operating condition, so as to assess the effect of its magnetic field on the health of pacemaker wearers. The results showed that Bmax in the carriage without passengers is 121.246 μT, occurs near the window. In the carriage, the Bmax, Ein max and Jin max of heart and body, Vin at the pacemaker electrode of the passenger next to the window are greater than that in the middle of the carriage. The Bmax, Ein max and Jin max of passengers’ heart are 11.301μT, 1.613 mV/m and 139.030 μA/m2, respectively. The Bmax, Ein max and Jin max of passengers’ body are 12.597μT, 0.788 mV/m and 75.299 μA/m2, respectively. The maximum value of Vin at the tip of the pacemaker electrode of the passengers’ is 0.048 mV. The Bmax, Ein max in all tissues of passengers are much smaller than the basic limits of electromagnetic exposure to the public set by the International Commission on Non-Ionizing Radiation. Vin at the electrode tip of passengers’ pacemakers are less than the perception sensitivity set by the International Organization for Standardization. This work illustrated that the magnetic field generated by the pantograph is within the recognized accepted limits for passengers with pacemakers, but we still recommended that passengers wearing pacemakers should stay as far away from windows as possible.
