Cell Phones and Your Heart

Found this extract from an article written by Dr. Joel Kahn, completely unknown to me, but thought it is interesting...

"...........a published study of patients with clogged heart arteries due to atherosclerosis. Over 100 of these patients had an EKG performed while a cell phone in the off position was placed at their waist and then over their heart. Then the EKG was repeated while the phone rang for 40 seconds at the same positions. Turns out that the cell phone ring caused higher QT levels, which is associated with heart rhythm problems. "

We do have a member who is certain his phone kept in his breast pocket affected his heart rhythm.

It goes on to say that keeping your phone in your pocket, like I do, near your "private" parts may not be a good idea either.

He says distance is everything, so in a handbag is good. Not sure what guys can do except a man-bag? Looked at protective cases but it reads as though you then can't receive calls, not sure?

  • Very interesting. Having a mobile in my shirt pocket for circa five years in the early 2000s could quite likely been one of the contributors in my case. Then went onto clip on holder on trouser belt for a couple of years then trouser pocket!!!

  • Interesting post Koll. Recently I did a test to see if my microwave was leaking and it is. You turn off your microwave and unplug it, put your mobile phone in then call it. If it rings waves can get through.


  • Hi Jeanjeannie

    Yes understand you on this, but remember that your cellphone works either in the 800 MHz band (All networks) or 1800MHz (EE and Three) whilst your microwave works at 2450 MHz

    So whilst yes a microwave oven will act as a form of "faraday cage" it's not designed for the frequencies that you are in fact testing it with. Having said that microwave ovens do leak and you can get them tested for it.

    Koll your reference is also interesting, mainly because they talk about the phone ringing. Two things seems not to have been considered here, firstly that the background level of microwave signals has not been taken into account, even when a phone is turned off, the same level of microwave signals are in any one place, the phone itself does not attract the signal simply tunes into it once switched on.

    And then when the phone is ringing again I am not sure it's actually transmitting any of it's very low power signal (only around 0.4 watts) as at that point it's receiving not actually transmitting. When the phone is answered then it transmits firstly it's recognition code and then your voice back to the cellular network. (obviously not true if you have any form of GPS turned on as it transmits it's poisiton continuously)

    It could be argued that simply hearing a cellphone ring would raise your QT levels.

    So I think a good deal more research is needed here, and I have no doubt the cellphone companies have a vested interest so independence would be everything in the research.

    Just some thoughts


  • Thanks Ian,

    Out of interest, many, many years ago I had a little portable Sony tele, Trinitron. It hadn't worked for years but I kept it on the kitchen top because it was such good quality. Like all good electrical engineers, I hit it every now and again, changed the fuses, etc etc, but it was totally dead.

    One day I put my mobile phone next to it, inches away for no reason, just there was a space there. The phone rang and at that very micro-second, the tele went PING and switched itself on. This was one of those very early digital mobiles that interfered with a lot of equipment.


  • True. However I can vouch for the fact that the phones in the 90s and early 200s were no where near as good "emissions" and EMC as today's ones and also used different frequencies then. They interfered much more with devices and devices affected the phone more!!!

  • Now Ian, don't tell me you just knew those MHz bands! Gosh I must be so thick, cos I've no idea really what sort of power those numbers are.

    Right, so now I've no need to dodge out of the kitchen every time I use the microwave! Phew, sigh of relief.


  • Hi Jean

    I suffer from really bad cellphone connection at home, so had to research lots of things about the companies to try and get a better signal, and get switched wavelengths.

    Be well


  • You can (well used to) buy a home tester which is much cheaper than getting someone in. Try somewhere like Maplin (£3.99 - it appears to be a free delivery item as it appears not to be stocked in stores).

  • Thanks Peter.

  • Just edited the price - hit the 0 rather than the 9!!!

  • Still keep my phone in my phone in my t-shirt pocket whenever I go/went somewhere during the 14 months of no AF after my 1st cardioversion, and the 3 months since my ablation AF-free.

    Furthermore, I had my cell phone in my left t-shirt pocket for 8 years (CONSTANTLY) while on the road as a truck driver for 12 hours a day or more. I DID NOT never have AF, until I retired and only occasionally kept my phone in my pocket.

    One could conclude that my cell phone KEPT me from getting AF all those years.

  • The main problem when keeping your phone in your shirt pocket I've found is when you bend over and it slips out into a bucket of water, or down the loo 😫.

  • This has perplexed me for ages Koll , is that a builder's bum with a big bow around his waist? 😂

  • No, it's a cool cat wearing sun glasses, like they all do. But I see what you mean now you've mentioned it. Think I'll change my avatar 😎

  • No, don't change it. I was just joking. We have a large etched window at our house which depicts the castle and cliff just beyond us, drawn by myself. I was very proud of it until someone mentioned that the clouds look like Casper the ghost . For 25 years that's all I can see when I look at it. 😩
