Implanted medical devices are pacemakers, implanted defibrillators and similar. People with these devices may be particularly concerned about interference from EMFs, so we give quite a lot of detail here. See also a simpler summary and for information on how EMFs interfere with other equipment.
Advances in medical technology over the past 50 years have resulted in an increased number of patients who have active implantable medical devices (AIMDs). There are no longer the constraints there used to be on these patients and many are able to live active, full lives, including returning to full-time work. There are however electric and magnetic fields present in the environment, which can potentially interact with these devices.

Having spent a few short hours searching the FDA Web site, I found some interesting warnings. What I am finding is a few listed implanted electrical devices that react to EMI.
On the FDA Web site, it it is recommended to stay away from several household electronics, medical tests and procedures, high-radio frequency devices, cellular phone towers, and high-power lines in these listed products.
Interestingly, not all implantable electrical products are listed. The argument could be made that if a manufacturer wants their device to work properly, they would design the product as to not be affected by EMIs.
If I were in this situation, I would see the physician specialist who implanted my medical device. I would find out of there will be an interaction with EMIs relating to my specific implanted device if I lived near these lines. If there were to be possible interaction of my implanted electrical device from these lines, I would ask for this physician to write something on my behalf to present to the BPA. I would then get a lawyer to represent me in the case the lines were chosen to go near my home.

Section 11: Chronicle IHM Summary of Safety and Effectiveness
Electromagnetic interference (EMI) – Instruct patients to avoid devices that generate
strong EMI. Electromagnetic interference may cause device malfunction or damage. The
patient should move away from the EMI source or turn off the source because this
usually allows the device to return to its normal mode of operation. EMI may be emitted
from sources such as:
• high-voltage power lines
• communication equipment such as microwave transmitters, linear power
amplifiers, or high-powered amateur transmitters
• commercial electrical equipment such as arc welders, induction furnaces, or
Home appliances that are in good working order and properly grounded do not usually
produce enough EMI to interfere with device operation. There are reports of temporary
disturbances caused by electric hand tools or electric razors used directly over the implant
Electronic Article Surveillance (EAS) – Electronic Article Surveillance equipment such
as retail theft prevention systems may interact with the implanted device. Advise patients
to walk directly through an EAS system, and not remain near an EAS system longer than
Static magnetic fields – Patients should avoid equipment or situations where they would
be exposed to static magnetic fields greater than 10 gauss or 1 millitesla since it could
improperly trigger the device to capture data. Sources of static magnetic fields include,
but are not limited to stereo speakers, bingo wands, extractor wands, magnetic badges, or
magnetic therapy products.
