“…The main findings of the present study are (see also 34 showed in a large in vivo study of cardiac pacemaker patients that single magnetic fields pulsed at power frequency are able to cause an inappropriate mode switch and pacing inhibition in unipolar lead configuration. Bipolar sensing seemed to be rather safe in magnetic fields with a flux density of up to 100 µT.…”

Background-The number of implantable cardioverter-defibrillators (ICDs) for the prevention of sudden cardiac death is continuing to increase. Given the technological complexity of ICDs, it is of critical importance to identify and control possible harmful electromagnetic interferences between various sources of electromagnetic fields and ICDs in daily life and occupational environments. Methods and Results-Interference thresholds of 110 ICD patients (1-, 2-, and 3-chamber ICDs) were evaluated in a specifically developed test site. Patients were exposed to single and combined electric and magnetic 50-Hz fields with strengths of up to 30 kV·m −1 and 2.55 mT. Tests were conducted considering worst-case conditions, including maximum sensitivity of the device or full inspiration. With devices being programmed to nominal sensitivity, ICDs remained unaffected in 91 patients (83%). Five of 110 devices (5%) showed transient loss of accurate right ventricular sensing, whereas 14 of 31 (45%) of the 2-and 3-chamber devices displayed impaired right atrial sensing. No interference was detected in 71 patients (65%) within the tested limits with programming to maximum sensitivity, whereas 20 of 110 subjects (18%) exhibited right ventricular disturbances and 19 of 31 (61%) subjects exhibited right atrial disturbances. Conclusions-Extremely

“…There are several publications on the topic including both in vitro and in vivo studies (Toivoinen et al 1991;Silny 2003). Two of them, in real exposure conditions, examined the operation of diVerent types of recent pacemakers in more than 300 patients exposed to a 50-Hz magnetic Weld (Trigano et al 2005;Souques et al 2007). The study by Trigano et al found that at a maximum intensity of 100 T, the devices switched intermittently to reversion mode 1 or inhibited stimulation in three cases among the 100 pacemakers with unipolar programming.…”

Abstract. The aim of article is to discuss interaction between stents implanted in the body of worker and harmonic magnetic field in the vicinity of electric wires. In last decades, a growing proportion of people has any devices implanted, to list: cardiac pacemakers, cardioverterdefibrillators. Recommendations of International Commision on Non-ionizing Radiation Protection (ICNIRP), and resctrictions imposed in different states, may exlude specific individuals from their duties. The autors focused on the situation, when the employee with stent, works in the immediate vicinity of overhead electric wires, cleaning with dry ice the electric insulators.
