I've noticed that the low heart rate notification ONLY notifies you when your heart rate drops below 50 for exactly 10 min.

If it's longer than that, it won't let you know. This is so against the purpose of this app.

Here is a screenshot of my heart rate during night time. You can see that it detected the first one for exact 10 min. But the second one, my heart rate was NEVER above 50 for one hour. The app never said anything. This is just one example. This app only does it when it's within 10min or equal to 10min. I've been observing this for a long time. I have a series 5 and the most updated WatchOs.

Apple if you read this, please fix this seemingly simple mistake.

Apple don’t read these forums (or at least not officially), and I don’t blame them. You need to report it through the proper channels on their website.

You realize this isn't a forum to report issues to Apple right? Also, a heart rate in the high 40s isn't necessarily an issue as people with high cardiovascular fitness can easily have a resting heart rate that low (mine actually regularly drops to 40 when I am at rest).

Can you please provide a screenshot of your settings in the Watch app under „Heart“?
You could a) select there 45 or 40 as well, b) it has to be over 10 minutes and c) your first screen looks to me like the Watch did send a notification. Because you didn‘t react, the deed was done and there‘s no point in repeatedly notifying you.

Mine drops to 39 sometimes when I am asleep. Normally around 50. My cardiologist said nothing to worry about. He says a slow forceful heart rate is desirable. My watch kick off when it goes below 40.

No, I set it to 50BPM. Yes, it has to be over 10minutes and the first screen is the only occasion where it did send a notification. But if you look at the second screenshot, that's another day, not on the same day. My heart has been beating below 50 for another hour and there was no notification! It's not about repeated notification. It just doesn't notify or marks the affected heart rate range.

Yes, I just wanted to share my finding and hopefully someone has the same finding. No, I am not worried about my heart beat at night. I just want to point out that the app doesn't work as it says.

I'm not worried about my heart rate. It's normal. But the app doesn't act normal. It should notify heart rate below 50 once it's equal or longer than 10 minutes. It doesn't do that at the moment.

For me, it works between the thresholds given :/ Really weird behaviour there...

I have to say mine works perfectly.

Check out April 20 LOL I didn't get much sleep that night from all the buzzing on my wrist!

But look at other dates... no problem when in happens...

so yours gives your notification even if the heart rate drops below the threshold for longer than 10 minutes??

Yep, just as it's intended! See poster before you, it's working for them as well.

That's weird, I wonder why mine doesn't work like yours. There is just one option which needs to be turned on and I did. Hmm. And also my heart rate monitor checks my pulse randomly, at night like every 4 minutes, sometimes 7 minutes. Super strange!

Looks like yours works as intended. And you must be an athlete for having such a low heart rate.

I have the same problem with HIGH heart rate not indicating anymore. I USED to get high heart rate notifications at night, IN the night if they were above a certain threshold.. I have it set in the watch app properly, and the HR sensor captures data that can show 120-135 bpm for several serial readings, over about 5-10 minutes while sleeping and yet I don’t get an alert, I don’t even get a note in the HR health app that shows them. But, I can see the data in the “show more data” area. Has this been disabled, or is it just falling?
