Key result
Induced voltage from 50 Hz electric fields is on average 10 times greater in unipolar mode than in bipolar mode for pacemakers implanted in the right atrium or right ventricle.

Does lead configuration and implantation position affect induced interference voltages on pacemakers exposed to 50 Hz electric fields in a virtual human model?
Computational modeling demonstrates that unipolar pacemaker configurations are significantly more susceptible to 50 Hz electric field interference than bipolar configurations, with induced voltages averaging 10 times greater.
Gerçek et al. (2017) studied Pacemaker implantation. 50 Hz electric field exposure was evaluated on Induced interference voltages on the pacemaker. Induced voltage from 50 Hz electric fields is on average 10 times greater in unipolar mode than in bipolar mode for pacemakers implanted in the right atrium or right ventricle.
