When exercising, my heart rate stops recording above about 135 bpm. The watch display for heart beat goes gray and maintains whatever reading was last captured. I do have afib. Thoughts?

See the 'What is AFib' section in:

Heart health notifications on your Apple Watch - Apple Support


The first (and simplest) thing to try if something isn’t working right is to restart your Apple Watch and its paired iPhone. If necessary (device not responding), try a forced restart. Both methods can be found here:

Restart your iPhone - Apple Support


If that doesn't help, the next steps would be to unpair and pair your watch again and restore from the backup just created. This should result in no loss of data. It deletes all temp and corrupted files and re-indexes the file system.
