OMG Marchlove, I've just read that paper in more detail and it is VERY interesting for me!!
I did have to google a lot of cardio terms and try to translate cardio-gibberish-speak

but I think the gist of it (translated into normal English) is....
.... that there are some people who are "hypervagotonic" - which means that their vagus nerve relaxes quickly and deeply and they have a resting pulse of under 60bpm. (The benefit of it is that they can recover from stress very quickly.) But these people, when they take berberine (this is where my translation might be slightly dodgy) - which slows everything down and relaxes your cardio system even more - can end up with the heart freaking out that it's too slow and compensating by going into weird arrthymias. (Which I can't spell.)
WELL GUESS WHAT?? Yours truly has a resting pulse sitting at the kitchen table of about 55bpm when I'm awake. When I'm asleep (
which is when the palps are happening now) it is probably even lower. (Can't say for sure because I'm asleep

) MOREOVER, when I had just come around from the anaesthetic after my endo surgery, they were very concerned about my low pulse rate and monitored me very closely. (I think it was even slower after the anaesthetic, like 35-40bpm or something.) I've always known I have a slow pulse and I recover really fast after exercise too - I remember discovering that during a school PE lesson when we had to monitor ourselves

I don't think berberine has caused ALL of this, because I only started it 3 weeks ago (I wrote it in my diary). But perhaps it is the reason I am not okay again, having stopped the estrogen now and having normal blood pressure now. Anyway, I will definitely stop it and we shall see. It sounds like the effects wear off quite quickly so if it is the berberine I should be okay in a few days...
Then I will be forever in your debt. I will have to explain some of this to the cardiac nurse calling me tomorrow as well

Maybe the appointment shouldn't be TOO soon, just so we know if this is going to work!
