Elec cables triggering svt?

Hi, I had svt and had an ablation 6 months ago and all seems well. One question that I have though which I'm not sure whether I'll get an answer but comments are welcome. I do a bit of cycling and originally noticed that my hr seemed to spike if I went under overhead elec cables (ones on telegraph poles, not on large gantries). Anyway, I've noticed on some recent rides that my chest strap hr monitor and garmin cycle computer show spikes again when I ride under cables. My question is, are the cables making my hr rise which is then picked up by my hr monitor or is my hr steady but the signal to the computer being influenced in some way to read higher? It tends to spike on downhill sections when applying very little effort.

I suppose one answer is to ride less and don't go near overhead cables.

Any thoughts?

It seems that it is still a bit controversial on here but all the evidence I've seen points to the fact that we are being subjected to a lot of electrical fields from cables outside and inside our homes as well as from mobile phones etc.

I have proved this in my own case by using a simple multi-meter. As I go nearer to an electrical device or cable my body's electricity is affected and my reading shoots up.

Some people seem to be more sensitive to it than others but it seems obvious to me that if we have too much electrical interference then our bodies (which are electrical devices) will be affected in some way.

I have been earthing myself by using an earthing mat to put my feet on in bed and a mousemat sized one for when I'm on the computer. I have my wrist on it as I type this.

I started off by just standing barefoot on the grass for half-an-hour before I went to bed and it helped me to sleep much better and also reduced my arthritis pain.

I then joined forces with a friend and bought 100 sets of mats to get them at a better price so that I could provide my family and friends with them at a good price. We got half each.

I have about 20 sets left now and am selling these on ebay (tem number: 133392863700)

If anyone is interested just go to ebay and make me an offer of £41 and I'll accept it.

They cost me £30 a set plus shipping so by the time I've paid ebay 10% and £3.50 delivery I'm not exacly profiteering am I?

Google "groundology" if you want more information. There is also a very good book by Clinton Ober, "Earthing". I got a second-hand copy of the first edition for £3.50 on ebay. It is a fascinating read.

Keep well

Keep grounded

I’ve decided that if my hr spikes each time I ride under a particular set of cables that cause it then I will set my loop recorder to also record my hr. This should give a definite answer as to whether it is my heart itself or just the garmin that is spiking. I know its not strictly what my loop recorder is for but if I only use it once it should be ok. Plus the cardiologist may be interested in knowing this.

Movement + cable + electric field = generator. The combination is inducing a current in your recording gear. Yes, the same thing will happen to your body, but minutely - you've probably noticed that you are not a particularly good conductor of electricity. If you go and stand under a pylon and manually check your pulse, I think you'll find no difference at all. The benefits of regular cycling are the important thing.

Noted. I suppose the next time it spikes as I cycle under cables I should stop and stay under the cables and see what my hr is. Just for info, I'm talking about cables that run along country lanes on telegraph poles in the verge to supply remote properties (not phone wires of course).

Some years ago I was on a large campus where the effect of underground 132,000 volt cables was called into question. I carried out measurements in a Nursery and footpaths, that didn't indicate a problem for healthy people. However, there were areas on a footpath that required caution if you had a pacemaker.

I suspect that some people have increased sensitivity to electrical fields. I was investigating a small fire in power factor correction equipment within a 400 volt switchpanel. The specialist engineer with me was affected by the magnetic field caused by electrical resonance. This was caused by a mismatch between the capacitors and inductors in the power factor correction equipment.

I think I may be more sensitive than most to electric fields.
