Over the weekend, Apple informed some users who signed up to its Apple Watch Heart Study that their contributions were complete.

An app notification thanked them for their participation and asked them to complete an exit-survey about the study, which first launched in November 2017.

The study in collaboration with Stanford Medicine was offered to anyone in the United States who was 22 years older with an iPhone 5s or later and an Apple Watch Series 1 or later. Atrial fibrillation, a common form of heart arrhythmia that is covered in the study, can indicate serious medical conditions like heart failure and stroke.

Participants were instructed to download and install the Apple Heart Study app and wear their Apple Watch. When an irregular heart beat is detected, a consultation with a Study Telehealth provider from American Well is offered, with some people asked to wear an ePatch monitor for up to seven days for further investigation.

Apple closed the study to new participants at the beginning of last month. In a prior announcement, Apple said the study would not end until January 1, 2019, but it looks as though the participants who received the notifications over the weekend all enrolled early, suggesting that data collection is winding down over stages as the end date approaches.

Rumors have suggested that 2018 Apple Watch Series 4 models will include enhanced heart rate detection features that could improve the smartwatch's ability to detect diseases linked to higher heart rates and abnormal heart rhythms, but what form the enhanced heart rate features will take remains unclear.

Design wise, the Apple Watch Series 4 looks similar to the Series 3 models, but the display will be bigger, allowing more space for watch faces and complications, as confirmed last week in an image leaked by Apple.

Come on, it's not that hard to analyze hearth rhythm with the current sensor. Sure, it's not EKG (that I hope will be added soon), but can be a great tool for an early alert so you go and visit your doctor.

I received the study complete message as well but I would not say that I enrolled early. I did not join the study until February 2018.

I enrolled on the first day and got my ending notice this weekend. I was surprised as I wasn’t expecting it. Had around 1750 samples. I wonder if anything will be published with the results in the next year or so?

I’m sure you’re not saying that because the current AW sensor is good, there’s no point in conducting research in collaboration with medical experts to make it even better. Because you’re not saying that, right? Agree that it’s a potentially great tool, and that Apple’s focus on the health implications of AW are commendable.

I am just saying that it sucks all smartwatches only show current heart rate and never analyze heart rhythm and I wish Apple finally added this so it becomes a standard.

The reason they don't is because they need data first. It's surprising, but the medical field really doesn't have a lot of data on "normal" because the data was really hard, if not impossible, to get. What are people's normal heart rate? What if you're really big? Really small? They have no idea, for the most part.

I'll bet it's unclear how accurate the sensors are, because to do that you have to compare your data against a known standard, and there isn't one. Do you really want to walk around with a nurse all day calibrating your sensor against a manually-measured value?

And even though the data from all these sensors is an amazing trove of data, but even you still need to correlate it.

The good thing is Apple and its partners are starting to do that.

Not sure the heart sensor works all that well for people with heart murmur. I was jogging at 165 then all of a sudden it reported 85. I think not.

The survey never loads for me. Just a spinning circle.

Edit: had to copy & paste the link in to Chrome to get it to work. Not ready to blame Apple entirely. Could be my ad blocker extension misbehaving.

Mine completed over the weekend. Not sure how 'early' of an enrollee I was, but it says I was in for exactly 120 days. I had forgotten that I had even enrolled!

Impedance matching is fascinating stuff. It's well-understood for electronic circuits, but there's little awareness of the applicability of the model in mechanical systems (especially biological systems). In his book Scale, Professor Geoffrey West discusses the application of an impedance model to our arterial network. You can see part of the discussion from the book here. He's primarily talking about the geometry of the branching of arteries, but the frequency-dependent behavior of the heart over time -- the focus of this study -- is a critical component. West also discusses why Tesla's AC design for power grids was superior tech -- Edison's DC design would never scale.

I highly recommend this book/ebook.

[doublepost=1535997392][/doublepost]Sorry hit the button too soon. I have been on the study only since 6/20/18, 76 days and 256 reports. My wife has been on it even shorter and we both got the completion survey. Odd

It does that for lots of people especially when you are moving around. When it does that the lower number is usually about half of the actual rate I have found.

Guess I’ll find out when I put on my watch tomorrow morning...

I’ve started making a habit of going watch-free on weekends, and this is a long weekend for many of us in the US. Really, I should put away *all* of the technology at the same time... but removing the watch, with its constant notifications and reminders, does seem more relaxing (especially since I will walk away from my phone for longish stretches).

Also got the notification about the study ending for me. I wonder if we'll hear more about it at the Sept 12 event.

Hmm, this is a good idea. They need a activity monitoring only mode where the watch monitors your vitals and stats but does not notify you of other things.

I, too, got the message about completion. I'm probably too healthy! 1799 contributions. No warnings of problems, but I wish they would just let it continue.

Had 5-6 times a day the elevated heart rate message for weeks, went to doctor and he didn’t take it seriously, cause with his EKG at that appointment everything showed up as fine.

When I’m at the gym this also happens sometimes and I’m confused.
