Really obvious high heart rate notifications not working?

Hi. I've had a series 3 for about 3 years, I bought it because I wanted to keep a check on some irregular heart rhythms I was experiencing (possible Afib). For a couple of years it was regularly registering high heart rate notifications whilst I was sleeping. I would go from my regular 60BPM resting heart rate to 140BPM or higher, the watch would record this for 30 - 60 minutes, sometimes more than once per night, before returning to my normal resting rate. A corresponding high heart rate notification would also be recorded.

Since May 2019 no high heart rate notifications have been recorded despite the heart rate recorder showing these heart rate spikes perhaps once per week.

Yes, I have checked all the settings and been through the heart rate notification setup repeatedly. There is no obvious reason why this feature no longer works. My notification threshold has been set to 100 and also 110 BPM, heart rate has been higher than 120 whilst sleeping recently but still no notification!

I've tried a full reset and reinstalled apps on my watch, hard reboots on both watch and iphone (I'm using Iphone 6). Both watch and Iphone are fully up to date with IOS. I'm at a loss, it's just not working.

As a side question; I've read that it's possible for Apple watch to read BPM incorrectly due to movement during exercise etc and the reading is usually low. Is there any possibility that the BPM could incorrectly read high? I'm still not sure these heart rate spikes I'm getting whilst sleeping are genuine. Whether genuine or not, Apple watch should still record the high heart notification.

Cheers

Hey Drewberry2. It's nice to know I'm not the only one with this issue but sorry you're as frustrated as I am with it!

The watch used to send HHR notifications when I was asleep no problem so it can only have been 'programmed out' with an update around a year ago. I thought the whole point was that the notifications only occur when we were at rest/motionless for more than 10 minutes - when sleeping is precisely when you'd want them to be logged!!

I'm going to post in a separate message the name of the additional O2/HR monitor I purchased to confirm or disprove the Apple HR monitoring. I don't know if Apple will allow this on this board, I guess if you don't see my next message they've prohibited it...

Best

Rob

I posted earlier in this thread, like others was initially concerned because heart issues are on my radar, but over time I’ve been less and less concerned with the random spikes. Last message prompted me to go look and I had a spike last night. Similar to others it was approximately doubled the previous reading and lasted almost 40 minutes, returning to a normal HR almost immediately. However this was the first time it dropped to a normal HR in the middle of the spike for just a couple minutes. Curious to see if there was a HRV reading during the spike I checked and sure enough there was a reading in the middle of the spike, exactly when the HR returned to normal during the spike. This tells me all I need to know, the algorithm was off, the HRV reading recorded the correct HR, and when the reading was over, it returned immediately to the incorrect algorithm.

Updating your phone and watch should be your first step;

Update your iPhone, iPad or iPod touch – Apple Support

Ok, that's 3 of us with the same problem. It would be helpful if we all confirmed our Apple Watch version and iPhone version. I'm using a series 3 watch and iPhone 6.

Same issue as described by several others. HHR for ~30 minutes and no notification. Curious if anyone has received an update from Apple or if they were able to prove the reading false.

Swapping to the other wrist also

helped in my case! That would seem to suggest a technical issue with the watches.

Has anyone double-checked with another device at the same time?

Is it true that you have such a high heart rate during the night when you sleep? Or does the clock show wrong? I wanted to know that.

have the same issue.

Liesbeth, thanks for your reply. I do not know when my watch is teporting elevated HR since I don’t feel anything unusual and I get the notification 30 min later, sometimes an hr later. Thanks

Still waiting for the holter results. Will post here when I get them.

Apple tech support installed a patch on my iPhone that resolved the issue, no more HR spikes

nice!

Apr 26, 2021 9:59 AM in response to DirksApple

As posted earlier, I had an identical problem. It took a second level technician to remotely add a patch to my watch. No more spikes since
