Just remember that while they constantly train hard their lungs are changing over time to increase the amount of oxygen into the bloodstream. That helps A LOT. They can have a lower heart rate to get the same amount of oxygen to their lungs.
I live at high altitude (6500ft/1981m) and my resting heart rate drops a full 15 bpm, into the lower 60s, when I’m just 3000ft/914m lower. It took a full year at altitude for my lungs to absorb more oxygen to where I wasn’t winded by doing physical activity. These guys train so hard constantly that they do it far quicker and can achieve incredibly low bpm.
The heart rate monitors built into the Apple Watch and other wearable devices can detect abnormal heart rhythms with 97 percent accuracy, according to a new study conducted by the team behind the Cardiogram app for Apple Watch in conjunction with researchers at the University of California, San Francisco.
More than 139 million heart rate and step count measurements were collected from 9,750 users of the Cardiogram app who also enrolled in the UC San Francisco Health eHeart Study, with the data used to train DeepHeart, Cardiogram's deep neural network.
Once trained, DeepHeart was able to read heart rate data collected by wearables, distinguishing between normal heart rhythm and atrial fibrillation with a 97 percent accuracy rate, both when testing UCSF patients with known heart issues and Cardiogram participants.
At a 97 percent accuracy rate, Cardiogram's study suggests the Apple Watch alone does a better job of detecting abnormal heart rhythms than FDA-approved accessory KardiaBand. From Cardiogram co-founder Johnson Hsiehublished in JAMA Cardiology this morning, the study confirms the results from a similar preliminary study done in May of 2017. According to Cardiogram, today's study marks the first peer-reviewed study in a medical journal that demonstrates popular wearables from companies like Apple, Garmin, Polar, LG, and others can detect a major health condition.
Atrial fibrillation, or an abnormal heart rhythm, is a condition that can be indicative of major health problems and it can lead to heart failure and stroke. Atrial fibrillation often goes undiagnosed, which is where the Apple Watch and other wearables can help. The Apple Watch won't replace a traditional EKG, but it can alert people to a problem much earlier than it might otherwise be detected. From the study's conclusion:In addition to studies on the Apple Watch's ability to detect atrial fibrillation, Cardiogram and UCSF have also been working to determine if the Apple Watch heart rate monitor can also detect conditions like hypertension, sleep apnea, and early signs of diabetes. Preliminary studies have suggested all of these conditions could be spotted in data collected by Apple Watch and other common wearable devices.
Apple has been working with researchers at Stanford on its own study to determine whether the heart rate sensor in the Apple Watch can be used to detect abnormal heart rhythms and common heart conditions. While in the study, if an abnormal heart rhythm is detected, participants will be contacted by researchers and asked to wear an ePath monitor to test heart health.
Apple Watch owners can sign up to participate in the Apple Heart Study by downloading and installing the Apple Heart Study app. Those who want to join Cardiogram's studies can install the Cardiogram app and sign up to join the mRhythm study.

What iPhones is this????
Not super on topic, but I use the sleep watch app and have been impressed by the info it picked up on. My resting sleeping heart rate is 10% lower on days that I do cardio.
Honestly unsure what that means (I keep my watch on for my alarm and the app came highly recommended) but it's cool that it's putting some perspective to the data collected.

I don’t drink, just like the logoPart of the problem might have to do with something similar to your avatar.
If I meditate I can get it down into the 50s. But sitting here, at work, it's 68 right now.
As someone with heart history (had open heart surgery to do a valve rework) PVCs came on a couple years later and scared the living crap out of me. I suffered with them for years. They're capricious things--highly frustrating at best, and downright terrifying at worst. It was only this past year that I learned a little more about them, and their relationship to something called the Vagus nerve. Here is a link to a blog post wherein a cardiologist explains. It's not a panacea, but reading this helped me a lot in being able to handle them psychologically. Although it seems like I am not as bad as a few of you here. I genuinely feel for you folks. Those things are crap.
I’ve had 1,036 heart rhythm contributions during the 112 days I’ve been in the program. So far none of them have generated a recommendation for me to see my doctor.

The Apple Heart Study App sends ‘Heart Rhythm Contributions’ to the study. Under some conditions they will send you a recommendation to see your doctor.

I joined the study because why not? At least it'll give them baseline data, and afaik I don't have the issue. It's' nice to put this stuff to use.
I wish there were more studies to join; I'd donate my (lack of) activity data and heart rate info if I could.

This happened to me for the first time last night and I kinda panicked. I was out eating dinner for a friends birthday and had a margarita and a corona and about 30 minutes after eating and drinking my watch alerted me. Kinda freaked me out a bit.
It may have been an error.
My Apple Watch always reports wrong data. In the middle of a workout it sometimes goes from 50bpm to 150bpm within a minute, sometimes it reports values that may be right, sometimes it is clearly wrong.
It may be my unit, I don't use it for fitness so I don't really care and don't want to bother asking for a fix, but it is simply unreliable as an heart beat monitor.
Hope they improved the reading with series 3 and continue to improve it with future releases, if it was reliable it would be really great.
This is a really helpful input. I workout with a chest strap too. And one reason I keep holding off on Apple Watch or any other wearable is because I don't trust that the wrist based monitoring will be accurate for intense workouts.
What workouts do you do?
This is tragically hilarious. Sigh. Things like this remind us that technology is great, but it isn't 'there' yet. 'A' for effort, Apple.
That sounds like there's something wrong. I've had one or two times since getting my watch last fall where the reading was out of whack, but over the last couple of months I've compared my watch with the readings from the exercise equipment itself (treadmill, elliptical) dozens of times and the two are never off by more than 1 bpm, and even that much difference I'm guessing is due to specific sampling rates and rounding errors.
Training for road cycling, mainly. I spend most of my time on a spin bike, on the bike trainer, or actually out on the road, when the stars align. I try and run occasionally but, without my bike computer in front of me, I have no way to compare, in real-time, the strap and Apple Watch.
Mine watch matches the heart rate displayed by cardio machines like ellipticals, ARC trainers, treadmills, etc, so if it's inaccurate, it the machines must be off by the same factor.

Right I've only had the watch for almost 3 years and have been closely monitoring my HR since then. I can assure you that I know at least as much (if not much, much more) as you do about the heart rate tracking features of the Apple Watch.
My point is just because you don't receive notifications of a high HR (from HeartWatch) doesn't mean you aren't having a high HR (it's like just sticking your head in the sand, because you don't want to know). HeartWatch doesn't actually take your HR, so much as grabs the HR data that your watch is already gathering. So it is literally impossible for HeartWatch to have been *causing* the high HR reading in some way. So yes there is a native "HeartRate" app, but that's irrelavent. Now perhaps (with the most generous interpretation), you are referring to the new WatchOS 3 feature that can also notify you if your HR is over 100. However, this feature only activates if you haven't moved in the past 5 minutes and if you have Series 1+ (no Series 0). So HeartWatch could certainly provide more high HR notifications if you HR is elevated when walking/going up stairs/etc. (and is the only way to get notifications for Series 0 owners).

Seems a far cry from 66%.
I find that it can’t detect my heart rate properly for the first 5 to 10 minutes of a workout. It usualy shows a grey number (I think that means it’s unsure) and/or jumps around. Eventually it gets it but I think it actually has to do with skin temperature. Before a workout, you’re generally cooler. I’ve also noticed it’s more accurate immediately if the room has been warmed (and therefore so am I) which seems to support my theory.
Anyone with knowledge on the subject able to corroborate this?

Exactly as said 10% talk about about it. Apparently its 18%. Only those who talk, as I also stated, wind up in statistics.
Very cool. I look forward to the day my tech can tell the doctors what I've broken.
I can definitely attest tot he accuracy of this including seated listening to tribal house music which affects heart rate of it moves you - like any music.
Moreover my heart is NOt in good shape to begin with.
