heart rate spikes

Let’s see if the new update 4.2.2 ends this problem. For last 2 night I had made the update all is normal so far

I tried , using a Polar H7 sensor with its strap and the result is the same...!!! spikes and erratic high values at start during 10-15 minutes...

Here's some more info on my setup:

Obviously my S0 was paired to my phone. My S3 cell + AirPods is the best thing since sliced bread. I love not having to carry my phone, so I don't.

I only notice HR spikes during a workout. With the S3 improved battery times, I'm able to wear the watch to sleep now. No problems with HR spikes at all. Since the HR is recorded a lot less in non-workout mode it's hard to tell if there's been data drops, but I did notice one period where HR was not recorded at all during a 2 hour period of basically doing nothing but putzing around the house.

I wear my S3 the same as the S0, the strap is quite snug. I can get my index finger under it, but not all the way through.

Place your iwatch on a desk and select the heart rate. Strange my desk is alive and well at 72 and then it spikes all over the map, so when your watch is not making contact the readings are meaningless and go all over the map causing concern for many.

Apple Engineers please insert a few lines of code to validate if the current t reading is within reason compared to the last couple of readings, and if not look at the next reading to see if the spike is continual. If it is then it’s a valid reading, but if not you need to suppress these spikes as they are garbage and are of no value to anyone. A simple validity check will resolve these spikes and provide us all a useful heart rate monitor.

Currently in my opinion the iwatch heart monitor is of no value to me and should be ignored until it’s addressed with a validity check.

I am having this issue during activity where it spikes, drops really low, or just drop out all together. I have confirmed its an error in the watch because I wear a garmin on the other wrist and can confirm the apple watch is having problems with the heart rate monitor.

I have a Series 2 watch and my watch started alerting me during the night (waking me up) that my heart rate was spiking @ 120+bpm versus the usual resting rate in the low 50's. Quite disconcerting and definitely didn't facilitate a restful remainder of the nocturnal hours.

The watch is less than a year old - fitted correctly - with reasonable battery - latest OS - so I can only assume it's the latest version glitch everyone else is talking about. Not ideal - here's hoping it gets fixed asap.

The watch clearly has no idea of when its accurate or when it is not. I can assure you there was no reason for these odd measurements. Cost me an expensive cardio visit & tests & the conclusion by the cardio was not to put any credibility in what the watch was reporting. Told me to toss it, but I like having the LTE for calls without the iPhone. So disappointed in the watch.

Same problem here!!!! Randome spikes for less than a minutr and then they come back down. The other night i noticed it was reading between 100-177 during the night so I panicked. Came to realize that i was not ever waering my watch so do knot know what it was reading .

I do believe it’s acurrate at least in mornings. It as the person before me said he had a 24hrs device connected and while Apple Watch said he still had spikes the medical device said he didn’t had at all. I have told this to my cardiologist and ran me tests and said was all fine bust as he saw me that I was still quite unsure we told me he will put me a holder one day long

Mine are both. Get as low as the 20’, and highest I’ve seen was 471. Normally no higher than the mid 300’s. Mine all happen during an event (my chest is pounding, I get confused, tunnel vision, and sometimes passing out). They don’t record to my phone, and cardiologist says it’s not possible to go that low or high. I’m not typically doing anything when this happens. Watching tv, working at my desk. Event only happens on the high heart rate.

I get those spikes sometimes while i’m sleeping but for the first time yesterday it lasted for almost an hour from 151 to 67. Because of this i’ve been seeing a cardiologist and spending a lot of money. I’ve done 2 stress test, echo, more than 12 EKG’s and nothing. Next think is to wear thr holster to check thoses randoms spikes at night. It never happened during the day. My resting hear rate is always good. I’mhere panicking and wasting money because of this.

I have the exact same unsettling experiences almost daily . I do have the watch for health reasons as I have SVT but it is rare but I like to know what my heart rate is if it goes up over 140 and doesn’t come down. That aside this faulty readings are makes me a nervous wreck with the alerts , i do feel they are relate to erratic arm movements cos really I would know if my heart was 156bpm, I’d feel it .

I’m close to getting rid of the watch as it has become the friend that turns on you from time to time lol

My excursion lasted 10 minutes while asleep bouncing from at rest 58 bmp to as high as 127

Yup. Go to the Genius Bar armed with dates of the random super high readings from your health app. Have your watch replaced.
