iPods and Pacemakers Don't Mix 152
fermion writes "The Register reports a study that indicates that iPods and pacemakers do not get along. While there do not appear to be any long term effects, iPods disrupt the operation of the pacemaker. It is noted that such effects have not previously been observed as iPods do seem to be popular with the pacemaker-wearing population."

how can they possibly be doing this, and it not be a problem for other players?
Well, for one thing, the touch-sensitive scroll-wheel is somewhat (though certainly not completely) unique. They use capacitive touch sensing. They utilize a low-voltage, low current AC voltage to measure the change in capacitance when you move your finger over the sensor. The googles say 102kHz is common.
My "second generation" nano produces a high-pitched noise whenever it's on- it's noticeable if you have it within 2 feet or so of your head. I'm pretty sure it is the inverter that generates the AC current, but if it's 120kHz, that shouldn't be possible, unless there's a resonant frequency in the audible range.
Maybe the sensor just happens to use a frequency that confuses pacemakers. Now that Apple is aware of the problem, they might do some testing and change it on future iPods.

With that in mind, this article taught me something new. I had always assumed interference was related to the wireless nature of pacemakers. My son's is regularly re-programmed via a wireless device set anywhere near his chest. I had assumed if there was a problem it would be related to whatever memory was being programmed. The ipod article suggests the interference is just an interruption between the device and its leads. They suggest the interference won't cause lasting problems once the patient is separated from the interfering device. That's not something that was in the 50 page booklet that they provided with the pacemaker.

The real concern is why pacemakers are made so they are susceptible to such interference. What happens when a user is exposed to an intentional RF radiator [wikipedia.org], which would be expected to put out much more power, and consequently cause problems at much greater distance?

The heart's electrical signals are very weak, so the pacemaker's sensing leads have to be incredibly sensitive in order to pick them up. Unfortunately, any ungrounded wire is an antenna, so that hyper sensitivity means that they pick up noise, even from sources that meet FCC regulations. Since the exposed lead has to be in physical contact with the heart at some point, there's no 100% effective way to eliminate the noise. It's a known problem with the very concept of a pacemaker.

Regarding sensationalism... (Score:5, Interesting)
msuave: Yes, a pacemaker or defibrillator is essentially inside a faraday cage already. They are generally titanium or steel encased, and designed to resist most radiation fields that are encountered in everyday life. However, faraday cages are not perfect, and the pacemaker has to have leads come out to thread into the heart. Just as you can use your cellphone inside a metal plane (also a faraday cage), some degree of radiation will be seen by the pacemaker electronics. In general, these devices are programmed by placing a wand over the device which essentially communicates by RF to the internal device -- if it was a perfect cage, it couldn't even be reprogrammed except by physically accessing the device (e.g. minor surgery.)
AC: Agreed regarding the sensationalism. Our practice tells EVERY pacemaker and defib recipient a list of things they should and shouldn't do. We counsel patients to hold their cellphone in their RIGHT hand and only crunch it between their right shoulder and ear, as almost all pacemakers are implanted on the left side. In general microwaves are ok, and patients are given a letter and card for the airport, where they can be wanded. Quite clearly, if somebody puts another RF emitting device RIGHT ON TOP of the implant, it could cause some interference. No, this is not unique to ipods. Again, if you actually talk to grandpa, I'm sure he knows this, especially if he was implanted by us. :) This "research" is quite ridiculous.
Finally, agreed regarding the description of the findings -- if it is just interrupting transmission of data to the programmer, this is a lot less dangerous than scrambling the internal signal seen by the pacemaker. The pacemakers are designed to recognize noise, again for the expected interference as noted above, and can handle this using many filters (e.g. something at 60 Hz is probably NOT coming from your body.)

RF shielding is a big deal. Just look at the nice Faraday cages used to enclosed MRI scanners. It has to be RF quiet because that is the actual imaging part of the system. The magnets just make things jump to higher energy levels. When they fall down they emit a signal detected with an RF scanner.
I would imagine there should be some form of RF/EM shielding on something so critical as a pacemaker.
