Is this my imagination?

I've had my PM 4 months and just ran into what I think is a new interference for me. My husband and I have side-by-side computers in an office in our house. I always sit at mine, and he always sits at his, and I've never had any problems with my PM while working on the computer. Today he was doing maintenance work on my computer, and 3 times during the day I sat at his computer. Each time my heart started beating erratically (pauses, then stronger faster beats, and pauses again) and my breathing felt "off". For some reason I didn't think much of it til it happened the third time. I moved away from his computer, and my heartbeat returned to normal immediately. He hypothesizes it might be the modem or wireless router which are located right by his computer. I haven't heard any warnings about staying away from computer components. Is this my imagination?

Well, maybe it was just your imagination -- once again --
running away with you.
I tell you it was just your imagination
running away with you...

laaa laallaaa. darn song stuck in my head.

I read a post similar to yours awhile back; the same symptoms as you. I cant remember what the exact post was though...I'm going to take a look and search the archive section and see what I can find. Did you always have this wireless router that near you before? But since you move out of the way and it helps, that sounds connected somehow, but I'm no expert. I'll try and see what I can find. Sorry! I know, not really helpful. Please keep us posted.
take care,

Valerie is right

Valerie is correct in saying others have mentioned a similar reaction to this. Unfortunately, I can't find it in the archives, either.


you did the right thing

It is possible that the wireless radiofrequency signal was affecting your pacemaker if you were too close to it (the router). Generally, there is the 6" rule - cell phones, ipods, etc should be kept at least 6 inches from your device.

You did the right thing to move away from the source of interference. Perhaps your husband can move the router farther away, or go wired since your two computers are next to each other.

Is This my Imagination

I find this a very interesting topic since I have had strange feelings in my PM with a few electronic devices. I am curious if anyone knows anything about the Wii and whether it has any effect on the PM. We bought one a couple of weeks ago and while it is great fun I am not sure if it is the cause of some of the additional irregular heart beats. I have A Fib which is getting much worse lately.

This HAS happened to me too!

by bambi - 2007-06-06 12:06:39

You know, I have had this happen to me so often, that I guess I've learned to ignore it along with innumerable other things! An interesting side note though, I had my pacemaker reprogrammed a month ago. Basically, they have me paced 100% on top, and are not allowing any of my own underlying rhythms to have any "say", since it causes all sorts of problems in my ventricles. Before this change, I couldn't get on the computer without experiencing the same symptoms Cathryn does. Since the changes in my settings though, I don't notice it nearly as much! Weird, huh? Also, I was recently using a headset in a large theater to communicate up to the sound booth, and I couldn't believe how out of whack my heart went!

Does the Wiimote interfere with pacemakers?

Hey Nuka.

I had heard that it does, so I went searching, and I was able to find this article:

Does the Wiimote interfere with pacemakers?

Filed under: Rumors

The rumor floating around this week is that the infrared Wiimote interferes with pacemakers. While nothing has been confirmed or denied by Nintendo, it makes for some interesting conversation.

Some signs were spotted at the Nintendo World event in Japan warning older players but there is still no word if the rumors are real. If the grandparents, great-grandparents or anyone esle in the family with a pacemaker wants to get in on the games, family members beware. You could end up with a real life Trauma Center on your hands. No one wants that!

So, there you have it!

Pacemakers and Wireless (WLAN) Interference

by LDHAND - 2007-10-19 10:10:07

I don't think it's your imagination at all!

I just bought a new wireless laptop (with radar to detect wireless networks as I'm out in the real world), because you know, I just can't wait to go out and get all hopped up on caffeine at the closest Starbucks and Google the heck out of my new wireless laptop! LOL! I also bought a wireless router to set up a WLAN in my house to share my broadband internet connection with my laptop.

As soon as I set everything up and got it turned on and connected, my pacemaker went crazy! I had to shut off my wireless within five minutes. My symptoms were: an intense burning sensation around my pacemaker, pressure on my sternum (it felt like someone was sitting on my chest!), a feeling of strangulation in my neck, and palpitations. It felt like I drank a whole pot of coffee, which (despite my joke about Starbucks,) I can't really drink more than a cup of a day. If I didn't have a pacemaker, I would have thought I was having a heart attack. I turned my wireless on and off several times, and every time it was on, my symptoms returned. (I even had my husband turn it on a few times I didn't know about, just to see if it was all in my head; it wasn't!)

I have a complete heart block due to an AV node ablation gone bad, so I am 100% dependent on my pacemaker. I don't know if that's why my symptoms were so intense? I had to put an ice pack on my chest to numb out the pain.

I have spent the last week searching the internet for info. on all of this, and I have seen numerous complaints from people with medical devices and Wi-Fi interference. I've read several reports about studies between the two.

They all say that despite the fact that they both share the same 2.4 Ghz bandwidth (the ISM, or Industrial Scientific and Medical band), the newer medical devices should not receive any interference from wireless networks. However, they all state that they cannot guarantee anything! And they also say to stay at least 11 cm, or about 6 inches away from the wireless device. (I'm at least 1-1/2 feet away from the little radar switch on my laptop when it's actually sitting "on my lap." That's as close as I got to anything wireless that I'm aware of.)

Since this world is rapidly becoming a wireless world, I am very concerned about my future well-being as I go about my day to day routine. Wireless networks are in doctor's offices and hospitals, both of which I've been spending a lot of time in lately! I just got done wearing a Holter heart monitor for 24 hrs. so that my doctor can see if they can figure out what's going on. I'll post a follow-up with any info. they tell me.

If any savy tech-heads out there happen to read this message, and you have answers or solutions to this problem, PLEASE post a comment!!!

Good luck to all of you who might be having similar problems with interference!


WiFi interference

by harley - 2009-02-06 04:02:12

I work in the wireless industry. I don't have a pacemaker yet, but it is indicated. My answer is more technical than experiential or medical.

Usually, WiFi shouldn't hurt you, at least not as much as a cell phone. WiFi only transmits when it needs to as opposed to the cellphone that's transmitting all the time you are connected and with higher power.

Indoor WiFi is strictly regulated by the FCC (Federal Communications Commission). If you want to make sure about the device, look on the label and there will be something there that says, FCC and Class B. If it says Class A, stay away from it.

As for the "radar" feature, you might look for some options. Either the computer just listens (so no RF issues) or it "polls" for the access point. A poll is like the game "Marco Polo". Your computer sends out a message to have all of the wireless connections respond to your computer. You might be able to turn off the "poll" feature. If that doesn't work, get a free copy of netstumbler from This will show you where your possible wireless' are without causing any problems.

Way too techie. Sorry for the long message. If I find out any more "real" data, I'll get back to you.

real research

by harley - 2009-02-06 05:02:35

OK, I found the link below that shows the same thing we were all talking about.

If you have an issue with a laptop, you can buy a USB based WiFi client and a USB extension cable. This should help get the distance from your pacemaker. If you choose to do that, remember to disable the WiFi radio inside your laptop.

Your not alone

I to feel funny when I'm around wireless connections too. my father just bought a printer with wifi & there's a router connected to the computer, my daughter has a laptop & we where trying to link it to the printer. when i walked into the room. i felt sick & my heart raced & got a bad headache. i just felt weird. so i left the room & went to the other side of the house & felt better. as i walked back to the computer room. i got sick again. i know i'm very sensitive to my pacemaker. when i go to the dr's & he checks it i feel the same way. what can i do?? help!!

even stranger

by kimberkitty - 2012-07-31 01:07:22

I have the same problem. I thought I was going nuts.

But I have an added problem. I think my pacemaker/defib
is also interfering with my computer. I'll be on and the whole thing just freezes. I didn't even think of this until, I had to use my husbands laptop. All of the sudden it started freezing like my desk top. And it's never done this before. Anyone else have this problem?
