Animal thresholds suggest possible EMI risk from low 60-Hz currents; leaves open human applicability and need for prospective validation before practice change.
What are the 60-Hz contact current interference thresholds for implanted cardiac pacemakers?
Numerical modeling demonstrates that 60-Hz contact currents can cause interference with unipolar and bipolar pacemakers at thresholds of 24-45 microA and 63-340 microA, respectively.
Dawson et al. (2002) studied Implanted cardiac pacemakers. 60-Hz contact currents was evaluated on Interference thresholds for unipolar and bipolar pacemakers. 60-Hz contact current interference thresholds for typical sensitivity settings range from 24 to 45 microA for unipolar pacemakers and 63 to 340 microA for bipolar pacemakers.
