Tachycardia can Low Dose Naltrexone (LDN) Help?

My friend developed tachycardia once to twice a day without physical exertion.  It starts suddenly. Normally normal EKG, and BP. Will LDN help in such condition?

Michelle Moser: I'm not so sure that LDN is the primary medication that I would jump into right here. The issues with tachycardia that happen once or twice a day without physical exertion could be a result of spikes in cortisol, which could be an adrenal issue. There could be changes in thyroid function, there could be a lot of other things going on. It could be even a status of do you  have enough micronutrients. What's going on with potassium, sodium, and magnesium? That sort of thing.  
LDN is not going to change a micronutrient deficiency. LDN is not going to change initial effects on adrenal or thyroid production. So LDN would not be my go-to in this situation. I think it would be much more effective and certainly quicker to get into more of the blood chemistry that is not being mentioned in this question. Yes, an EKG is normal, and blood pressure is normal, that makes me think we need to look at what's going on elsewhere in the body, that is having a dramatic impact on the heart.

Stephen Dickson: I have a little bit on that one actually. Post COVID we're seeing a very surprisingly large number of people with something called POTS, which I know we've talked about, that doesn't necessarily fit what they've said there. But the importance is when you sit down or stand up and your heart rate goes into this tachycardic bizarre sort of flutter position, and then I think an awful lot of doctors are under diagnosing that, and what we're finding with POTS is LDN does seem to help a wee bit, but we put them into the hyperbaric chamber that does that almost seems to fix them within a couple of hours in fact. 

Michelle Moser: It's good to know, it's nice to hear about other therapies that are happening elsewhere in the world as well, because in the US things can be a little conservative or mainline. We don't hear a lot about hyperbaric oxygen chambers being used.

Stephen Dickson: We've only really had one operational since the end of last year, and actually I wasn't really a believer in LDN to begin with, just like I wasn't a believer, now I see a majority benefit from this hyperbaric chamber.
