heart defibriillator

The doctors that put it in should be able to advise far better than us. I think high voltage is not good for electronics. So Testing spark would be ill advised. Magnetic suppression plug wires might also be desirable installed to reduce RFI. Jim
 


My cardiologists gave me all kinds of restrictions but what do they know? From various on-line sources I found that running my chainsaw really is OK as long as I keep the engine 24 inches from my defibrillator. Welding is OK so long as I don't go over 95 Amps. They told me when working on a car to not lean over the distributor. Sorry but magnetos never came up. You can trust your life to the advice that I have gathered over the internet because I am still ticking after nearly four years!!!
 
Did they give you any restrictions with regards to running things like chainsaws, weed eaters, hedge trimmers, and such? I'd follow those same restrictions because the principles are the same.

Or just search the internet until you find a site that tells you what you want to hear.

Long story short if you start feeling funny, you probably shouldn't have oughtta done that...
 
If your asking because the Dr. who installed it can't answer your questions, I would be looking for a different Dr. If your asking because you don't like the answers, hey, it's your heart and life, do what you want. Either way, this is not where I would be looking for answers. Just because something works for someone else doesn't mean your situation is the same.
 
You missed the good 'ol days when those puppies first came out.
Made in Orygun.
It would zap yer asp so hard you'd fall on the ground.
First solution proposed was to emit an audible noise to warn you, 30 seconds before, to get down on your hands and knees to brace for impact.
My wife was impressed. She simply asked, Why don't you turn down the voltage?

You might have her to thank for no broken bones from the fall due to the ZAP!

God, I miss her.

Your microwave might also be an issue.

You need to talk to the device manufacturer, they are the ones responsible for the RFI / EMI testing of the device. The Dr. will only give you a punt of "don't do that" on things they don't know.

Some years back there was a guy on the welding newsgroup that got an ICD and unsatisfied with the generic punt responses did extensive RFI / EMI measurements around the typical processes of concern to the point that the device manufacturer and their engineers discussed the finding with him.

I forget the exact details but most of the processes were safe, a couple had to be careful to keep separation and possibly HF start processes were too risky. Probably something to be found on the 'net. Memory is fuzzy but recall Don Foreman possibly?
 
(quoted from post at 12:01:32 11/07/23) Why in the world would you ask that kind of thing on a site like this? Good grief.

Because you will get far better answers than from the Doc who knows nothing of the manufacturer's RFI / EMI testing.
 
Oddz are near zero that the device manufacturer did EFI/RFI testing around 75-year-old tractor magnetos.

So in reality NOBODY would know the answer to the question. If they do, and it's not the answer you want to hear, they're not going to be able to tell you.
 
Probably not, however if you do some research you can find the results of testing that was done and make meaningful comparisons.

The reality is that the risk is pretty damned low that any interference would actually harm you. Perhaps you might get an unneeded jolt but the chances of not getting a needed one are very very small (fail-safes, watchdog timers, etc.).

One has to make their own decisions on risk tolerance and for this one given my knowledge on the subjects I would accept the risk of continuing my normal activities and paying attention for any signs of issues. I would also demand access to log data from my device so I can review it directly.
