I hope they add the resting heart rate feature to the S0 as like you said, it is most definitely software based.
I actually bit the bullet tonight, and ordered a 38mm Space Gray w/ Gray Sport Band GPS+LTE Series 3. Not just for the resting heart rate reading (I sent Craig Federighi an email earlier today asking him why the S0 does not support it, no reply yet) and not really for the LTE, but more so for the ability to be able to swim with it and the added performance gains/battery improvements. I have wanted the waterproofing for a while now! I just went with the LTE model because I figured why not have the flagship model of the watch when I am going to be getting the flagship iPhone X in Space Gray as well. I have not decided what to do with my S0, might keep it, might sell it, might give it to my mother.

"I'm just glad the feature that alerts you when you experience an elevated heart rate (100bpm or higher based on your configuration) when you have been inactive for 10 minutes or more is available on Series 0. For anyone who experiences regular tachycardia (rapid heart beat) episodes, this could help them track when they happen, what they were doing at the time, and what other factors may have been involved (stress, medication, caffeine, etc.). All useful information for a doctor."
I forgot to mention this. I am very happy like you are they at least added this to the S0. This will help save more lives than the Apple Watch already has, and help people get diagnosed properly. So, I at least applaud Apple for that move!

Resting heart rate no data

I'm not convinced that S0 owners are missing anything important with the lack of Resting HR. At least, based on my experience with an S2, the Resting HR reading is useless.
I've been using Cardiogram for a while now and typically, my resting HR is around 75 to 80. This lines up with a quick look at my daily HR chart.
However, with the wOS4 implementation of Resting HR, it basically takes the lowest HR reading of the day, and report that. For me, the lowest reading of my day is always during sleep, where I get down in the low 50's.
I'm not sure what algorithm Apple is using to determine Resting HR, but I'm pretty sure that my HR while I'm asleep is not very relevant.

Sure it is. Both numbers are relevant, but resting HR is traditionally measured after a long period reclined without movement. In general, it was suggested that you take it in the morning before getting out of bed. Because of noise the data, I wouldn't take the lowest HR number you get over night--and Apple doesn't--but it makes sense to take the mode of the lowest range of HR readings.
I'm not sure how Cardiogram calculates its "resting HR." It is usually in the mid to high 50's for me, and often jumps 2 or 3 beats after a run. I'm not sure how an elevated HR during a run is in any way relevant to my resting HR. It shows a higher "resting HR" after a busy weekend day doing yard work than after a weekday at my desk job.
If you track resting HR over a long period you can see how it changes in response to training, illness, caffeine consumption, and improved/declining fitness. I came down with a cold three weeks ago, and I saw a jump in my resting HR a few days before I got sick, and it continued to be elevated for a week after my symptoms were gone.
That's what I'm saying. At least with me, Apple is using my sleeping HR as my resting HR. So if I drop down to 52 bpm during my sleep, Apple reports my resting HR as 52. The reported value might go up a few beats (to 54/55) during the day, but there's no point in the day where my HR drops down to even 65.
So I did just read that resting HR should be taken right after waking up, so maybe the AW knows when I wake up and takes a reading at that moment (or close to it). Then it reports that as the resting HR.
Then that leads to the question as to how Cardiogram calculates it. Also, what about folks who don't wear their AW to sleep?
Not sure if this is the right place, but I'm seeing a HR anomaly and wondered if anyone has seen this before I hit up the cardiologist.
At night, Ill get an elevated HR that goes from my normal sleeping rate of about 60 to 120 and just STAYS there for 1.5-2 hours. It looks like a box, goes up, locks in at 110-120 for the entire time and then 1.5-2 hours later drops back to 60.
thoughts? I was thinking some sort of sensor error, maybe sleeping face down, arm under pillow or pressure on the arm forcing flesh into sensor?
Or, some other physiological issue?

Most of the sensor errors I see is where the sensors just stop picking up your HR. If yours is showing an unexplained elevated HR of 110-120 in the middle of the night, I would be concerned, too. Your pillow should not be making this difference. Would not hurt to bounce this off your GP.
I agree with Newton's Apple that this is something worth mentioning to your doctor. If this is happening regularly enough to capture, your doctor can order an in-home sleep study where you wear equipment that takes all kinds of measurements that include heart rate, blood oxygen level, breathing rate, etc. I wore one to detect whether or not I was experiencing sleep apnea (I wasn't), but the results do provide a much more complete set of metrics for your doctor to review. They may also want you to wear a holter monitor for a period of time to capture your heart rate while you are awake as well.
I also wore my Apple Watch while I was wearing the sleep study gear, and the heart rate captured by the Apple Watch was very accurate. My Apple Watch readings matched the results (within 1 to 3 bpm) they provided when it came to minimum, maximum, and average bpm. Of course your mileage may vary with a wrist worn monitor. They work better for some rather than for others.
A lot of people experience occasional rapid heart rates during inactivity, but frequent episodes are always worth mentioning to a doctor. There are many reasons they can occur that are not serious, but it's always good to get a medical opinion. I think the new watchOS feature that can alert you to elevated heart rates during inactivity is really helpful. You can keep a log of what you were doing at the time, what you had been eating/drinking, your mood, etc. Of course if it is happening in the middle of the night you might not want to be awakened by an alert. You just want to check your logs to see when it happens during sleep.
Good luck!

I think there's a good chance it's a sensor issue.
But if you've seen it repeatedly, I agree that it could be something real. I occasionally see a stray high reading in my overnight HR data, but they're just isolated blips, nothing that sustained. Perhaps tighten it up a notch? Or even shave your wrist a bit to see if it persists?
