22) Do static fields affect cardiac pacemakers?




Description

This article is from the Static Electromagnetic Fields and Cancer FAQ, by John Moulder jmoulder@its.mcw.edu and the Medical College of Wisconsin with numerous contributions by others.

22) Do static fields affect cardiac pacemakers?

Effects on cardiac pacemakers have been reported for fields as low as
1.7 mT [73]. The most common effect was triggering of the asynchronous
mode; the effect is very model and orientation dependent, and in the
models tested normal operation resumed when the pacemaker was removed
from the field [73]. Some pacemakers also exhibited significant torque
was exposed [73]. For this reason current static field guidelines
restrict exposures for wearers of cardiac pacemakers to 0.5 mT
[50,58,59]. It would be prudent to apply this restriction to other
implanted electronic devices, and to prosthetic devices as well,
although not all standards are explicit on this point.
