| Abstract | In view of the omnipresence of electronic article surveillance (EAS) systems in daily life and the increasing number of patients with active implants, there is concern about adverse electromagnetic interference in particular cardiac pace-makers (CPM) and cardioverter defibrillators (ICD), which due to sensing electrocardial signals are particularly vul-nerable. To provide quantitative information interference of monopolar CPM and ICD by EAS systems operating at 8.2 MHz radiofrequency electromagnetic fields (EMF) investigations have been performed by exposing numerical ana-tomical models of pacemaker patients with implants at the conventional left or right pectoral sites and at the abdomen to magnetic fields of a simulated EAS gate source. Investigation of normal position in the centre and worst case with the back next to the gate showed that adverse interference such as inadequate sensing need not be expected at any position. This applies for conventional sensing thresholds even if the exposure span of existing EAS systems is taken into ac-count. However, if full use is made of the newly expanded exposure budget, adverse interference cannot be excluded. |
