Since in these days there are lots of different devices and appliances which are sending out all kinds of waves or radiation and different strengths (e.g. RFID scanners, induction cookers, Bluetooth, power lines above earth, security scanners, etc. ), I'd like to understand what of these influences in which strengths can influence a pacemaker.

Does anybody have a detailed reference for this?

  • I edited your question to remove the second question. You can make that a separate question if you wish.

There is something called electromagnetic interference (EMI) that can mess with electrical devices normal function. However, manufacturers can use certain materials to make devices with that can prevent EMI (however nothing is perfect; as per Murphy’s law, if it can, it will).

Here’s a link that discusses some of the risk factors of having a pacemaker and things that can cause EMI

Here’s another source to check out that talks about risk factors

You should really talk to a medical profession or even call the manufacturer of the pacemaker for more specific questions.

I would also say that the chance of EMI occurring depends on how close you are to the source. So WiFi throughout the house may not affect the pacemaker unless your holding the device right next to you.

  • The links you provided are very contradictory. For example, the first says there are risks with mobile phones, the other says there are no known risk except directly over the pacemaker. Oct 5 '20 at 7:27
  • Thanks for the links. However, I am looking for deeper detailed/technical/medical. I have read these high level advices, but like to gain a deeper understanding on how the electromagnetic influences occur in the cardiac device, what the results of the interferences are (e.g. "sensors deliver wrong information" or "computing unit in cardiac device breaks") and what the fallback scenarios inside the cardiac device are. Do you have insights to studies, etc. that she'd light on the details?

    @Bertolt Then what you're asking isn't a medical question; it's an electrical engineering question and would probably be better asked in the Electrical Engineering exchange. There's no reason why the average cardiologist would know the technical details of what effects EMI might have on the pacemaker's circuitry.

  • @ChrisRogers you say the links are very contradictory and use the cell phone example, however, both links state the same exact thing, that is to keep the cell phones from being right next to the pacemaker. Are you simply trying to discredit my answer cause it makes you feel better?

  • @dval98 What makes you think I'm trying to discredit your answer? All I was saying is that I saw a discrepancy in my view. Others are free to make their own minds up. Mar 5 '21 at 17:22
