Key result
Exposure of cardiac pacemakers to low frequency magnetic fields induces an electromotive force through inductive coupling that can potentially disturb pacemaker operation.
Why the study?
Does exposure to low frequency magnetic fields disturb the operation of cardiac pacemakers in vitro?
Does exposure to low frequency magnetic fields disturb the operation of cardiac pacemakers in vitro?
Low frequency magnetic fields can induce eddy currents in pacemakers, potentially disturbing their operation.
Alerts clinicians to potential magnetic interference in pacemaker patients; hypothesis-generating, requiring human studies before practice implications.
This paper presents in vitro investigation of the eddy current induction effects to the cardiac pacemaker exposed to low frequency magnetic fields. The method used in this study is based to the interaction by inductive coupling through the loop formed by the pacemaker and its leads and the surrounding medium. This interaction results in an induced electromotive force between the terminals of the pacemaker which can potentially disturb the operation of this last. In this article we present experimental results, analytical calculations and numerical simulations using the finite element method.

Babouri et al. (2007) studied Cardiac pacemaker operation. Low frequency magnetic fields was evaluated on Eddy current induction effects and induced electromotive force. Exposure of cardiac pacemakers to low frequency magnetic fields induces an electromotive force through inductive coupling that can potentially disturb pacemaker operation.
