    Hi I am getting a spike in my heart rate say for a second or three max gone to 203 which I would have noticed for sure... I have not had readings like this on my first Apple Watch.

    I did a check up with a cardiologist cause of this...!!!

    I did some searching on google and there is a thread on Apple where people have the same issue as mine... below is the link.

    Most of my problems with my HR on the AW is it not picking up my HR at all or it being very low. I do not think I have ever had it do a very high reading without a reason.

    If in doubt, next time count your pulse on your wrist for 15 seconds and multiply by 4 to confirm.

    Then it is an erroneous reading. No way your watch can do your HR in a few seconds. Just ignore the high reading as it has to be in error, haha.

    My Scosche armband does this (not directly related to your 200 bpm thing), except, it pops out 2-3-4 14,000 bpm readings during a workout. Throws off the chart horribly.

    My watch, initially I had a problem with it not reading my heart rate at all during exercising (this is why I got the armband). Tightening the Apple Watch's band fixed this completely for me so now it is perfect. So every time I do a run, I tighten one notch.

    Helps that with the armband, my battery usage is easily 3x than just using the watch alone, so I just use the watch now.

    Just a erroneous reading like your URL said. The HR function on the AW is far from perfect and you should only use the readings as a guide. Your cardiologist should have confirmed that.

    He said he would not count on the Apple Watch reading in the first place :) but as per apple and others they are very accurate... not the case here I am sure as i did not feel a thing any of the times the spikes show up....well.... Apple better fix this if its an software issue.

    I have owned every series of the Apple watch and the HR sensor has not changed. There are time when no matter where I wear my watch or how tight it just will not do my HR correctly. It may show half of what it should read or just a blank and showing nothing. For some the AW is very accurate and when my works right, mine is very accurate but there are times you will get an erratic reading.

    The Apple watch is far from perfect when it comes to checking your HR. When it does work for me it is very accurate but 10 minutes later no readings again. This is no medical device, far from it.

    I would probably chalk it up to the fact that all of us humans are a bit different from the next. Ever since I was a kid, nurses have had a hell of a time drawing blood. Had one point in high school where they had 4 needles sticking out of my hand (failed attempts), then tried on the inside of my arm and failed even there a few times.

    My Fitbit HR was unable to get a heartbeat on me - and when it did, it was incredibly inaccurate. The Apple Watch has been by far the most accurate, but when I first got it, it couldn't get anything during workouts. So I have to tighten the band a notch for it to read my HR while jogging.

    Like Newtons said - it's not perfect, and since we humans are all a little different, some of us will have different experiences with it. My scosche armband, supposedly very accurate, has its issues even. :/ Hopefully the technology will improve.

    It is possible your watch has noticed a mild tachycardia.

    I used to see something similar. I think it was due to a loose watchband. I had the leather strap and it was uncomfortable when it was tight. I changed to the Milanese band which I wear tighter and see that rarely.

    Thanks for posting this! My watch was doing one of these few-second spikes once a week or so. I figured it was the watch malfunctioning, but you do wonder. But I figured it out.

    I started paying attention to what I was doing when it happened, and I realized it was when I was doing my hair. I have really long, curly hair, and sometimes I finger curl it. Imagine wrapping a really long piece of string around your index finger of the hand that you wear the watch on. When you do that, your wrist makes a tiny, quick flicking motion as you wrap. I started turning on the heart rate app while I was finger curling my hair, and it's reproducible - I can make my heart rate spike to levels that are not happening.

    I had read that the HR might not be accurate when you are doing vigorous exercise with a lot of wrist motion, but I was thinking like burpees or other big motions. This is just very tiny little motions. Larger motions, it seems able to handle. I think it's actually OK when I'm exercising - if my HR goes up to 170 then, I'm usually earning it. I think I've read that it uses a different sensor when you're "at rest", so it must be that one that's not OK with quick wrist motion.

    I will add that I have really small wrists, so the watch fits snugly, but it's about as wide as my wrist, so maybe the fit isn't "typical". It's also very hard to get blood out of me, which someone else mentioned, so maybe my pulse isn't the easiest thing to read.

    Anyway, if this is happening to you try twisting something around your finger. It seems like it might also happen if you were using a screwdriver, or any other light twisting motion.

    I sometimes notice a spike when I first put mine on. Your heartbeat is 96! Just kidding, it's 75 a few seconds later.

    I got my first warning last night watching Avengers Endgame. Literally doing a certain point of the climax, my watch vibrated with the alert that my heartrate was close to 150BPM (even at the gym doing a hard workout I generally peak at 125).
