leanardthelemming, perhaps your HCP should read up on the vast amount of information available on the internet, starting with this Which report which refers to The British Heart Foundation’s advice.
Interesting article. It does, of course, state that there are many types of pacemaker and that one should seek medical advice - which is what I did.
Also, as a physics specialist who has taught medical physics in the past, I do have some vague idea as to how induction hobs work, and distance from the source is, of course, an important factor as the field strength falls off quite rapidly with it. Also, a normal pot-stirring position puts me quite a distance off axis as well.
But at the moment when I asked the question, the HCP was looking at the data (i.e. evidence) that my device had just uploaded to her computer and that, coupled with the fact I notice no problems when cooking, is good enough for me.
Of course, this does not mean your device won't be affected.
I do think, however, that we should always be sceptical about things we read. Articles like the Which report are likely to err on the side of caution, and even official, printed, medical advice may contradict that given by individuals.
