It's true that low COQ-10 can cause muscle aches, which are a common side effect of statins. But if the alternative is a heart attack, then I'd probably rather take the statin and supplement COQ-10 if it's low. Given that the

What are the advantages of reinforcement learning over DPO (Direct Preference Optimization)? My understanding is that the DPO paper showed it was equivalent to RLHF, but simpler and more computationally efficient.

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 sta

FWIW, I didn't find this to be a bottleneck and it probably helps detect upvote rings.

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 ty

Yeah -- in addition to inappropriate measurement technique, "white coat hypertension" can cause elevated blood pressure readings. And, of course, you have the fact that the American College of Cardiology (ACC) updated their blood

I'll bet blood pressure readings throughout the day will be analogous to the data we get from CGMs (continuous glucose monitors). You get lots of spikes during the day. Given enough data pairing continuous blood pressure with major eve

I'm not an expert on European law, but the requirements listed here for a CE mark indicate that the EMA reviews the safety and performance of the device and audits the manufacturer's quality systems, similar to the FDA: https:&#

We have an app which delivers medical care, and Apple let us on but required proof of medical licenses, malpractice insurance, etc. Medical apps are allowed, but there's a higher bar for evidence.

They announced they're targeting 150 countries, so there will likely be CE-mark approval coming (this is the EU equivalent of the FDA).

The Apple Watch 9 and Ultra 2 have a neural engine (GPU), which may be helpful if the sleep apnea detection algorithm uses a neural network. Those models also come with a third-generation heart rate sensor, although that part may not be req

It wouldn't surprise me if they did the latter. The oxygen saturation sensor is fundamentally just another optical sensor with a different wavelength of light -- so if you feed all three wavelengths, plus the accelerometer, into a neur
