Apple Watch Reading

[crafte]

Has anybody seen a reading like this from your Apple Watch? I don’t think it’s Afib - no alert saying it’s Afib. What makes it even more weird, is when I first look at my heart rate, it just shows the low rates. The higher rates don’t appear until later, after the fact!

What you're looking at simply shows what probably is a normal variance of heart rate during the day due to different life factors, such as different activity levels. It does you not say if you were in a fib or if you were not in a fib. Not to worry.

Thanks for your reply. What I’m curious about are the two rows of dots while I’m sleeping from approximately 12:00 to 7.

They show the minimum rate. It looks like a range. Do you get af alerts. My iwatch tells me. You can adjust range in settings. This picture of mine shows dots. Which is minimum. My pacemaker is set to 50 at night and 60 during day which is clearly shown by the dots. Have you had a heart recorder. 100 is high for sleep.

101 isn’t that high and it may not have been AF. Your heart rate is still influenced by the parasympathetic system even when sleep. It could just be NSR but a little fast.

have a look at the image see the top, the ‘D’ for day now tap the ‘H’ for hour and you’ll get a more accurate timeline.

[crafte in reply to OzJames]

Thank you for your response. I have looked at the hourly. Again, why am I getting two sets of dots?

Two sets of dots

Do you have Irregular Rhythm alerts turned on - or Afib History? If you do, the watch should report whatever possible Afib it detects. As I understand it, the readings are not continuous, but rather discrete samples, and alerts aren't generated unless irregular beats persist for several minutes. As for the range of dots, you might have had a stretch of ectopic beats.

[Buzby62 in reply to RussJun55]

More like several hours to trigger an alert and sometimes not at all. AF alerts are pretty unreliable really but was how I found I had AF in the first place. It had missed many episodes before alerting me.

[Buzby62]

Looks like you’re having fast beats and slow beats at all times, I guess that could be AF or another arrhythmia maybe, try looking at Heart Rate Variability (HRV) and drill right in to the beat to beat measurements. You may need to use the Browse button in the Health app to find HRV

Have you done an ECG with the Watch ? That should show what is going on.

Hope that helps

Best wishes

Have a read of this support page

Thanks - I have read that. Checked fit, cleaned the back of my watch. I’ve had several (6-8) readings like this. It’s always at night and just seems so weird that I’m getting the high and low readings that are pretty consistent at the same time. When I get Afib it wakes me up with the pounding of my heart. I’ve tried ECG and haven’t caught anything unusual.

[Buzby62 in reply to crafte]

I’ve had anomalies with the occasional unexplained high rate and I put it down to the limitations of the optical sensors taking the background heart rate. I’ve observed it is often twice my actual rate at the time so maybe one beat is being seen as 2 and hence giving the false reading approx twice what it should be.

I don’t wear mine to bed but if I wake with an episode then I put it on just to record an ECG or two.

I would take a screen shot of the data and show it to your doctor so they can see if there is anything that should be checked out. I discovered I had AF by showing Apple Watch data to my doctor when something abnormal showed up.

U could try to go to the very end of that page and select Show All Data. You will see single measurements. The same in HRV page, going to the very end u could search All Data for same time frame and check details. Maybe u get some insights. If not, go to your closest apple shop and ask for a watch check.

THANK YOU!!! I hadn’t drilled down that far before. I think the mystery is solved. The second set of dots gets added later and is the set of higher dots. By drilling down, I can see that the second set of dots is coming from Sleeptracker which is my fancy bed frame. I think I will trust my watch! I’ll sleep better tonight not worrying anymore. Thank you everyone for your help!
