Q: My heart rate fluctuates wildly during workouts (from 55-120bpm) in a matter of seconds..

My heart rate fluctuates wildly during workouts (from 55-120bpm) in a matter of seconds..  This happened in 'Indoor Cycling' and 'Other' workouts on the apple watch

 

I know the lower readings can not be accurate

 

Anybody else seeing this ?

    There are many things that can affect the accuracy, and there are many people seeing strange things on the heart rate monitor function following 1.0.1 update, so check the basics like fit being snug, etc and otherwise hopefully it will be corrected with a future update.

    Happens to me too. I found the heart rate monitor to be nearly worthless during workouts. In the middle of a workout, it measured a heart rate of 45. I gave it another try while lightly pushing the watch against my arm, and first I got a "try again" and then it was something like 48. I suspect that sweat might be affecting the sensor, because outside of workout sessions, the measurements are accurate.

     

    It's a bit strange to me though that the software behind the sensor would believe that it is getting accurate measurements when the data coming from the sensor must be completely erratic.

    It seemed very accurate with 1.0 but since 1.0.1 I get divide by 2 readings. I'll be out for a brisk walk with my heart rate between 120 and 144 and all of a sudden it will read 65. It will stay at 65 for a number of minutes and eventually jump to 133 or something. All of this is with a sport band tight on my wrist. The watch barely moves on my wrist since it is so snug. Tonight while bowling I noticed it had taken my heart rate while I was sitting. It said it was 39 BPM. I wish that were true and that I was in that good of shape.
