Hi Dan,
I saw this come across my inbox this morning and immediately thought about the
conversation on this list that you started in 2022. I thought you might be
interested in the lead article on the pacemaker study.

I'd suggest that you have your relative call Support at the pacemaker/defib
manufacturer. On a slightly different project, I found a lot of on-line
information about device immunity, and I think we even called Support and got
additional clarifying information

Hi Dan,
So the issue here is that pacemakers are designed to be stopped with the use of
a permanent magnet. When the cardiologist is checking the operation of the
pacemaker in the office, they will stop it by placing a permanent magnet on the
chest of the patient. They can then see how

Subject: RE: Heart pacemakers - Vulnerability to EM
I am no expert in this subject, and some of what I am about to say is hearsay,
but here it is for what it's worth.
Safety levels are generally based not on field strength, but on power density.
However, these levels are set
on a pacemaker rather than
directly on the body itself. Clearly, if you disrupt a pacemaker then it is
the pacemaker that has an effect on the body.
I believe that the susceptibility depends greatly on whether they are external
pacemakers or implanted pacemakers. The implanted devices are much less

Can anyone point me in the direction of any standards that would cover the

The focus of my interest is for pacemakers that are likely to be found in

The closest I've found with my own hunting so far
ANSI/IEEE C95.1 is for human exposure but it does not cover pacemakers.
Draft VDE0848 part 2 (1991) covers 30 kHz-300Ghz and does have limits for
pacemakers. An English translation is available from BSI.
There is no relationship between the limits for human exposure and limits
for pacemakers
What is the ANSI standard or regulation for safe limits for people
exposed to electromagnetic fields? How about people with pacemakers?
I've been informed that there may have been a German study done in
1988 concluding that these field limit values could be used

Brian, in the EU all pacemakers must comply with the immunity requirements
of EN50061/A1:1995. There are no real requirements in the US.
Pacemakers must not malfunction when a 1V peak to peak sine signal with a
frequency range of 20 Hz-500 Hz is applied to a tissue interface simulation
circuit
How do I know if a product MIGHT interfere with a Pacemaker or not? What types
of emissions and levels are Pacemakers sensitive to? Does a product evaluation
check list exist to help determine this.
I know nothing about Pacemakers. BTW, we manufacture laboratory and IT
equipment.
Thank you
No. Amendment 1 of EN 50061 contains the right EMC requirements for
pacemakers. Similar EMC requirements have been included in EN 45502
family for other kinds of implantable medical devices.
