in this forum I saw a note suggesting you clean the sensors. This might fix erratic heart rate readings it said.
I tried it using the lens cleaner for my glasses. That helped a lot. It still is erratic but no where as bad as it was. I guess sweat affects it and the body oils build up.

Or you can use a small amount of rubbing alcohol or microfiber cloth would also assist in cleaning it. But my heart rate sensor has been plenty dirty before, and it works normally as it should.

Tracking HR on the Apple Watch IS erratic for some and no amount of cleaning will help.

Cleaning it is the easy part. Relocating the veins in your wrist so they can be read by the sensors more easily is more difficult.
