EMI from electric shavers etc

Thats a bit of a messy installation, not a single cable clip ;O)

Keep with the beat Michael.

regards Martin

Both mains and battery shavers have to meet the same EMI/EMC emissions levels. This includes emissions from leads.
The advice to keep electrical / electronic items away from implanted devices will be predicated on those items meeting the mandated emissions level.

That's where, if the heart is running too fast (arrhythmia etc) they speed it up to slow it down? Mine does that - though I never notice. They do test it at the pacemaker clinic and tell me its about to happen and i can feel it (just barely) then.

It's the thought of the big one (defib) that scares the bejeepers out of me.

[ I really can't see why the thread needs to be locked. Do we really all need protection from ourselves just because someone might (a very big might, in my opinion) be foolish enough act on medical advice he received in the Model Engineer Forums without checking a truly medical opinion first? ]

No ... CRT is a little different

I will post something more about it later, if the thread is still open.

P.S. ... We discussed the ‘defib’ option in some detail ... and I declined

Is this the best place to find this information Sam? My guess (and it is just a guess) is that there will be more variation in the sensitivity of different types of medical device than different brands of shaver. Perhaps the device (medical, not shaver) manufacturer, the hospital that carried out the procedure or the British Heart Foundation (who have a leaflet which includes recommended separation from different electrical devices) may be much better placed to advise you.

As promised: Here is a little more about my CRT

In early 2016, it was known that I had a ‘Left Bundle Branch Block’ ... but this was considered fairly benign, and it was more important to fix the plumbing [quadruple Coronary Artery Bypass Grafts]

In late 2016 the electrical problems became significant, and they fitted a conventional 2-wire pacemaker.

In 2018, I suffered ‘Severe Heart Failure’ [the ‘volume fraction’ of pumping should be about 70%, mine had suddenly dropped to 17%] ... Fortunately, fitting a 3-wire CRT device; re-using the original two, and adding the tricky third wire, worked very nicely. The basic problem was failure of the heart’s electrical system, which was causing the left and right ventricles to pump in anti-phase ... so the blood was just washing between the chambers !

This page features a brilliant animation showing the problem:

Yes, it does refer to arrhythmia ... but my device is active on over 90% of my heartbeats, so it’s really doing most of the synchronisation work.

Here’s a short snippet from one of Tom Kenny’s excellent books:

Many years ago I was given a pacemaker as a curio, it was recovered in a routine exchange, a scope showed it was still ticking away for many years after the exchange. My mother recently had a pacemaker fitted and I accompanied her to her first checkup, it appears they are very sophisticated devices now, they are interrogated with a wireless connection and seem to transmit a log and live data, clever stuff.

Apologies, Bandersnatch ... I’ve just noticed that ^^^ seems rather abrupt

What I meant to write was more like:

No ... my CRT is a little different

Too simplistic perhaps but why not just wet shave, millions of us do it?

If nature had intended us to shave we wouldn't have evolved beards...

Correct, I've only shaved twice in the last 50 years, once to get married (she said she wanted to see me without a beard, then asked will it grow back in time - NO), second time to pass a respirator fit test to go into a particularly unpleasant environment at work. The test back then was to put on the respirator, tighten it up, sit in an enclosed space into which the lobbed a teargas canister. If you didn't dash out you passed. I'm sure it's a bit more scientific now.

A couple of my friends are wood turners and both have fungus. The general advice is don’t bother with a face mask as the dust gets past. As a result one of them has bought an air fed face shield.

I worked with a chap whose take on beards was ‘ why would you encourage on your face that which runs rampant round your a**e’

Mike

No apologies necessary, Michael - I wouldn't call it abrupt. "Unequivocal" perhaps (which is appreciated).
