"Longitudinally collected HRV metrics from a commonly worn commercial wearable device (Apple Watch) can identify the diagnosis of COVID-19 and COVID-19 related symptoms." Having first-hand experience, I can confirm that my heart rate was WAY up, and my pulse-ox was WAY down when the virus was at its worst. I used the pulse ox value to make sure I was getting in good breaths (and yes, I know there is a hefty margin of error on these consumer devices.) I use a Garmin, but the sensors are pretty much the same on Apple Watch. It would be pretty easy for the device to tell I was sick but probably impossible to tell I had COVID-19 instead of the Flu or a bad infection or maybe pneumonia.

HRV is neither pulse rate or blood oxygen. It is variations between heart rates, and the reason this is fascinating is because HRV is a significant leading indicator, long before the other indicators which are lagging. HRV is increasingly becoming a very important metric. When your body is under stress (mental or physical) the heart because tightly sequenced. Under normal, healthy conditions it has slight lags and leads based upon breathing and other conditions. This post will be dead given that dang is a pathetic bitch and a *horrid* moderator, but for those enlightened enough to use showdead.

In my case HRV went down almost 30% before I started to have symptoms with 50% of average on the worst day. Resting heart rate went up 35% on the worst day and respiratory rate went up 18%. But only HRV was obviously changed before I started to feel symptoms and became infectious.

umm speaking from personal experience (comparing garmin reading with hospital oximeter), garmin is waaaay inaccurate sometimes! Maybe it is because I always shower with it, or maybe it just loses accuracy over time. Didnt give it a second thought and just disabled the sensor.
