laptops and notebooks

Post by bekki » December 26th, 2012, 4:00 pm

Hi everyone. hope all had a mavelous Christmas. Christmas day we were al sitting around wih the grandkids and everyone was on a notebook or laptop. I was playing with one of the notebooks and had it sitting on my lap. after a new minutes i started feeling funny, kind of lightheaded and felt like a really slow heart rate. i put the notebook up and rested for a few minutes. later i got back on the notebook and felt the same way again. i suddenly thought maybe the the emf was high in the notebook or something. i looked online and sure enough the emf is quite high in laptops and notebooks and should not be used in the lap. I use a pc all day at work and have no problem. has anyone else had this problem? wondering if it could set "sparky" off or cause damage? it was quite disappointing as i was going to get myself a notebook so i could sit on the couch and surf on the computer. i hope to discuss this with my "electircian" at my next appointment. any ideas?

I'm sure there is a more tactful way of saying this, but I think you are being paranoid. Let me add, this is not an unheard thing among us bionic types. Laptops, ipads, cell phones, etc likely are no cause for alarm beyond just worrying that they might be. If you want to feel a bit better on this one, try a forum search on "personal vibrators" which had a huge amount of interest-never could understand why.

I see there is health issues by using a laptop on your lap but I could not find any emf issues with the ICD. Not saying there is not but if someone finds information please let us know.

Oh rest assured i am not paranoid, use pc, cells, etc all the time and live a most normal life amd have never had anything so far give me cause for concern. just going my my docs advice not to be around emf as it could damage the icd. found many articles on the internet about the high levels of emf on the laptops and notebooks and not to use on your lapfor long periods of time even if you dont have an icd. so i was wondering if anyone had a similiar experience. i was advised by the doc also no to use electric back massagers that were used when i went to the chiropractor and also the massage chair at the beauty salon. so maybe my doc is the paradoid one, huh? giggle!!! i have a biotronix, dont see many of that type here, anyone else have this brand?

They are a German company best known at this time I believe for having an ICD explode although I have never looked through the actual details. I myself prefer the Boston Scientific who may be best known for lying to their users about the safety of their devices, but I think that was pre merger or pre sale. Then either might be better than the group that sold faulty leads that may or may not work and if they do may or may not cause inappropriate shocks, but the law probably does not like me referencing anything to do with Danny Thomas. In short, while you may be in severe congestive heart failure, it may be wise to check for immediate news regarding your device manufacturer and what they are up to.

Right now, I would tell any EP that I would only accept a Medtronic device. Let me add, I am not the Flying Camel guy and I have never met him.

Again, my own semi informed opinion-there is NOTHING short of electric welding equipment and or laying over your running car engine's alternator that would adversely affect your device. EMF's are likely the least of your malfunction worries.

You felt what you your instincts.

You could still buy a notebook, just put it on a tray/table, not directly on your lap.

My daughter has an Apple Mac IPad and Laptop Computer. With both of these devices she can attach metal things to the covers. They are magnetic, and you will notice that the power cord does not push in, but is held there by a magnetic force. So therefore what you experienced could possibly be the magnetic current from the machine itself, especially if it is an Apple product.

As for the other devices that affect our devices, I was at a checkout at a local supermarket and came over very light headed, and felt quite weird. I asked the girl where the security monitors were, as they were not obvious, and yes, they were under the counter right where I was leaning. The only indication of anything being there was a red light. Now if this is my imagination, then why did I ask where they were, as the feeling I got was similar to the feeling I get from the obvious ones. To say that we 'imagine' or are paranoid about these things is offensive, they do happen and if you have never experienced it yourself, then try and stand beside a shopping centre security device and find out for yourself. If you don't get a reaction, then good for you, but some of us do.

thanks so much ozchrissy for your observation....that is exactly how i felt, light headed and "wierd" and yes i think paranoid is offensive as each person is different and things effect our own devices differently. i have never even had a remote thought about things that effect my device, dont live a different life than i did before "sparky", never had a sympton or complaint before, although i am careful about things my doc has told me. :) I am so glad you understand.

and yes Suzanne I am going to buy a notebook anyway, cant hardly live in this time without one, huh? I will just keep it at arms lenght, that is the only way I can see it anyway :)

thanks for all the input everyone, have a great day!!

Bekki, I recognise the problem. I have it sometimes and it is coming from my neck. Sitting more upright helps. Emt can not be the problem unless the laptop is really broken and even then when it is put up you ICD (which makes typing and reading quite difficult).
My name is Gijs but in English you can call me Gilbert as this might be easier te remember :-)

I'd believe it, and it might well be one of those things you can't duplicate, that it had to do with the other laptops and wireless and broadcasting on the network and yadda yadda yadda.

This is our way, we have to show care around electronics, and once in a while the electronics remind us why.

It's been a few days, I'd try it again. It might be some quality of that particular laptop, for that matter.

I upgraded in the last few months from an old anchor of a cell phone (had 8 years) to a smartphone. This phone had an option of buying a magnetic type charger where you just stick the phone on it and don't have to plug it in to charge. I was going to order it when in researching it I found that it did emit EMF. Also I would have put the charger on my nightstand between me and my Merlin when sleeping. So I decided against purchasing the wireless charger, and have just been plugging it in the old fashion way to be safe. Whatever you are comfortable with is what you should do:)

Actually, this reply may seem a little strange to those that know me on this site. I am unable to provide any medical proof of this but as Suzanne succinctly says we know our own feelings. I do get ectopic runs, and sometimes frankly they are quite horrible. It really could be just in my mind but sometimes when I am on my laptop or notebook for some time (over an hour) and it is 'near' to my ICD I suddenly get bad runs. I move away from the laptop and it subsides. On a couple of occasions recently I have gone straight back to the laptop and the run picked up again and stopped when I moved away.

Yes, it may be a huge coincidence; but it may not.

I listen to doctors, but I listen to myself also. I am not 100% sure either way about the affect if any my laptop/notebook has on my ICD. I would not be surprised if it had no effect, but I would not be surprised if it did have an effect. I have an open mind on this.

I shall monitor the situation and log what occurs I think.
