This sounds like reflex tachycardia -- your body wants to ensure blood is flowing to all the right places, so it raises heart rate to partially compensate for blood pressure falling. Reflex tachycardia can be a normal response to certain types of blood pressure medications, like vasodilators or diuretics. Beta blockers are a different common type of blood pressure medication that attempt to lower both blood pressure…

I won’t be a user of your service, but wanted to share a bit of feedback on the page you shared. On that page, I didn’t see any definition for POTS (though I know what it is or if I were someone else, I could’ve searched online). The page mentions a CHOP protocol without a link or explanation about what it is. I think the page could do better with some simple explanations or at least a guidance on symptoms and what y…

Let me second your comment. That webpage really needs to define POTS and give a brief explanation. It's written as if everyone knows what it is. I've never encountered the term Postural Orthostatic Tachycardia Syndrome until now.

This is super exciting, thanks for posting! I developed high blood pressure after Covid and have done a few 24h studies to better understand it. The traditional machines are super bulky, essentially like carrying a regular BP monitor around with a pouch that's strapped to you, maybe just a bit smaller. All in all it's far from convenient and can kick in at inopportune times. Having around the clock insights would hop…

Just curious if you BP was low/normal at night?

Not really, it was usually hovering right around the border of what's considered high blood pressure. As you might guess, the daytime numbers were off the charts compared to that. Luckily my body responds very well to the medication and a small dose is all I need to stay in a good range the whole day.

I'm a med device engineer and have watched the hopes and dreams of cuffless BP monitoring tech. I hope we get there as it will be hugely important. However, remember tech is only a small part of the battle. We need to figure out clinically what to do with all this new continuous data. I am very sceptical PPG alone will be capable for many reasons. Aktiia does indeed have European regs clearance. But, they don't have…

Plus gold standard measurements (ABP) are invasive enough that they're not used often for studies. Much of our available data comes from surgeries and a handful of dead dogs.

I have frequent chest pains as well since my early 20s! They tell me it is costochondritis but my inflammatory markers are always exceptional. I know what it is now and it is totally neurological, both issues. Wonder if you have noticed if you were neurologically sensitive to any types of foods?

Eventually they subsided, I don't even remember when, and I've never really had them since...unless I have reflux, which does happen for me occasionally. I'm learning I just can't really do coffee / caffeine though, I don't think it's ever really been good for me, it causes reflux and anxiety for me, but I just loved coffee to much. I gave up recently however! You might have heart burn occasionally too ?

I cut out caffeine & my chest pain completely went away & never came back.

You're absolutely right. This page was originally written for people searching for POTS, so we assumed some context. I've updated the page to link to pages we've written on POTS diagnosis and the CHOP protocol, so that it stands alone a bit more.

Thanks! Mentioned above -- I updated the page to link to dedicated articles on each of these.
