Q: Heart icon on watch fluttering

most of the time the red heart icon on my Apple Watch flutters.  Sometimes it has a steady beat.  My heart rates seem normal.  Is anyone else seeing this? It's a little disconcerting..

    Hi

     

    For the best performance from the heart rate sensor (as well as the Taptic Engine and Wrist Detection), check that you are wearing your watch with a good fit. Wearing it with the right fit (neither too tight nor too loose, with room for your skin to breathe) should be sufficiently comfortable, whilst also allowing the sensors to operate properly:

    Were you at rest when you looked at the heart rate glance and the icon fluttered? What I'm seeing on my Apple Watch is that repeated, periodic movements severely affect the heart rate reading, even when the fit of the band is just right and the correct heart rate is shown while at rest. For example, when I'm on an indoor rower, my heart rate always shows as between 70-80 bpm which is totally unrealistic - it should be closer to 150 bpm or so. When performing other cardio exercises such as running or cycling, the correct heart rate is shown.

    The watch is fitted properly and the icon flutters almost all the time.  There has only been one day in the last 2 weeks that it beat regularly, and only for a few hours. The indicated pulse rate seems normal (when I haven't had any coffee) and doesn't affect the fluttering.
