heart rate spikes

I decided to return to use my Polar V800 heart rate monitor instead of this inaccurate Apple watch... it does not help to use it, it is better the Polar....!!!

Yes I’ve had apple 3 watch for over a year with consistent heart rate readings. But in last week I’ve had multiple readings over 150! Then it goes back to normal 65-90 range

Same for me !

I have the brand new Apple Watch Nike Edition (no cellular) and i have many spikes during my run.

I also noticed that the hr is anormaly high during the first minutes of my run (around 170bpm, i'm sure i'm not that high !) and then go down near 140bpm, which is correct.

Of course i wear my watch correctly, not too tight or too loose...

I had the same issue with my previous watch nike serie 2.

It's very bad not to have a reliable hrm when you want to run depending on your bpm 😟

In Apple's terminology, the original Apple Watch range is referred to as "Apple Watch (1st generation)".

There is no such model range as "Series 0".

Apple offers the following resource for identifying Apple Watch models:

I'm having the same issue on Series 3 watch. First few weeks everything worked great (even tested it against a chest strap HR monitor and matched it perfectly). Then I was getting short spikes. But now I'm getting spikes that last 15 minutes!! Has anyone resolved this issue? does getting a replacement fix it? I wear it tight during exercise. This is a light jog I do all the time. I also checked with the apple heart rate app to rule out the 3rd party software and it was high also.

I’ve had an Apple Watch 3 cellular version for about 2 months now and I’ve seen two heart rate bursts (about a10 minute event) both times when I was sleeping so I couldn’t do a manual pulse check. I would just get the elevated heart rate notification in the morning. I never woke up and didn’t notice it either. I’ll let my doctor know about it but since it happened only twice over a two month period I’m unable to say whether it actually occurred or was a glitch in the reading.

Have you had any updates to your issue with the apple watch? I ask because i've been having heart rate spikes while sleeping (without showing the same issues during the day). I have a call into my doctor but trying to see what else others have experienced.

Stanford is currently signing people on for the Apple Heart Study, which uses Apple Watch data to look for abnormal heart rhythms in a large population. I assume Apple is looking closely at any behavior in the watch that would give false readings. At least, I hope they are. http://med.stanford.edu/appleheartstudy.html

Mine has spiked to 471 from sitting for an hour, the Dr says the watch is faulty. I was experiencing some sort of internal distress at the time, but it quickly failed. Did you find out anything further on this? Also while it showed on my watch, the data never made it to my phone.

I replied four days ago to your related question here, including providing links for contacting Apple Support if you believe that your Apple Watch may be defective:

Heart rate recordings

to me irá versión 4.2. Since 4.2.2 ir has just happened me once but that night was constantly repeating the alarm ( it was all night) so I woke up and run the hr manually and go back to 60s then alarm again while sleeping and again to 60s , at the end finally took the watch off and still got one alarm so maybe there is ghost in my bed. Lol

I'm curious if anyone has tried using a clear gel (perhaps like that used in ultrasound scanning) under the watch to minimize reflective artifacts. I've not ever seen heart rate spikes, although my exercise currently consists of brisk walks and riding my stationary bike. Spring is coming, though. I do see some remarkably low readings that I think are inaccurate (34 bpm? - I'm never that calm.). If you do try this, be careful not to use too much if your watch is not waterproof.

Thanks for the tip -- I tried wearing the watch a few cm higher (away from my wrist) and fully cinched down and that seems to help. My run this morning showed no high spikes at all (although it did show one low dip). Of course, this morning was warmish... the real test will be trying this in the cold.

I get the same thing with the dips. I'm amazed that apple hasn't responded or tried to explain how they are attempting to fix the problem. Like I said, the watch is great but definitely needs to be improved.

What series Apple Watch do you have? Mine is series 2. I understand series three is improved. I look forward to the 4th release, and hopefully it will have the algorithm worked out to calculate blood pressure.

I had the same exact issue. The first time it happened I actually thought something was wrong with my heart and went to the doctor. I used to have Fitbit Alta HR and it provided much more reliable reading than a $500 apple watch.
