Random Heart Rate Dips on Apple Watch

This thread has 4 pages of posts. The explanation is already provided. Did you read through any of the posts? I’m happy to provide my explanation again.

>>There is really nothing for them to look at. What some people here are experiencing are call outliers.

>>An outlier is a single data point that goes far outside the average value of a group of statistics. Outliers may be exceptions that stand outside individual samples of populations as well. In a more general context, an outlier is an individual that is markedly different from the norm in some respect.<<

In some individuals an outlier is a valid data point that is an indicator to a potentially serious issue and needs further discussion and analysis. It’s easy to design a filter to remove outliers but wouldn’t that underserve the individuals that need to be warned about a potential issue?

I think people that wear medical devices and general health indicators should seek the services of medical professionals and not rely exclusively on internet discussion forums. 😄 😄 <<

When this happens to mine, it shows it as reading as an ECG instead of streaming/walking etc when I check all data even though I have not started an ecg. I think this has something to do with the sudden dip and it seems like it is an issue with the watch

I've had this issue as well. Looking back in my Apple Watch heart rate monitor history, there have been multiple times when my heart rate monitor has spiked into the 150s, 160s, and 170s and it's not due to exercise. The worst was last week when the heart rate monitor spiked to 192 and back down less than a minute later while I was taking a shower. After that episode, I wore my wife's Apple Watch on my other wrist to compare. Both had unusual spikes to the 130s at the same time and immediately back down to normal while I was sitting down so it's not specifically my watch. I have also calibrated my Apple Watch heart rate monitor against UCSF hospital equipment and it is exactly the same readings - sometimes off by one beat but quickly realigns which is probably just a timing issue. I have an Apple Watch 6 and wear it using the same wrist strap hole every time. No tattoos. My normal resting heart rate is between 65-70 and most of the time the heart rate monitor is accurate. Seems like a bug in the software.

I also had Pp preeclampsia and that was the first time anyone has ever mentioned a low heart rate. But after some research, I learned that the magnesium drip that I was on for 24 hours does cause a lower heart rate. Maybe that’s the case for you too? My watch will have random lows in the 40s, but daily. And then go back to normal. My resting heart rate always shows mid-upper 50 but I’m sure these random dips aren’t helping. I’m paranoid too, hence how I got here!

Great to hear! Did they mention what type of symptoms? Just so I am aware if I experience any.

Your watch took readings every minute for 10 minutes? Or did it take a reading and 10 minutes later it took another? Can you please post the screenshot?

Currently awaiting a cardiologist appointment on 5/17 for the same concern!! I am 7 weeks postpartum and I did not work out AT all during my pregnancy so I know I can’t be having these random dips due to fitness level. The readings are never consistent enough to alarm me with the 10 minute setting. They’re random throughout the day. My heartbeat remains low consistently at night. Ranging from 50-60 BPMs. But what’s concerning is the random dips and sometimes spikes. Neither with symptoms.

Thank you. That’s the thing, prior to having my baby I barely looked at my BPMs unless I was working out. Not sure how long this has been happening for but I am more aware of it now because I had preeclampsia that got my son out via emergency C-section 2 months ago. My blood pressure was wonky until almost 3 weeks ago and that’s when I noticed my heart rate being “weird” as well. I pray it’s a lm annoying bug for the watch. We shall see next week with the cardiologist!

I had the exact issue of random dipping and it happens a lot of time. No symptoms so ignored it. I am not an athlete for sure to have such low HR while awake. My sleeping is lowest 50 and awake could be like 60s i guess.

Hi, any update? I am postpartum as well with the random dips. Just curious what you found out. I'm not having weird symptoms, I've just noticed it on my watch. I went from 80s to 50s back to 70s-80s today. I looked back and it has been happening randomly.

This makes me feel so much better. I honestly wouldn’t notice any dips or spikes if I didn’t look at the history and data. I truly am data driven person so this drives me crazy. I have dips from 41 to 175 yesterday. I thought maybe I had an afib episode and didn’t recognize it! But I never got any alerts and I had a great day. I wouldn’t have even known if not for the history. I do wear my watch extremely tight …. I feel so much better reading some of these comments.

I find it surprising nobody else mentions these multiple measurements in one minute like 16 or more. See photo. In this case how can a 4 sec measurement have any meaning. I have them all the time.or more!
