Hi @archer, I see that you have posted similar questions about dizziness and chest pains in a few other discussions. I have been concerned about atrial fibrillation's reported on my watch occasionally along with some irregular heartbeats. I ran across some references to dizziness and chest pain associated with Afib and was wondering if it might be something to consider.

Perhaps @oldkarl, @ch665296f, @reenj62 and @predictable have some thoughts or suggestions they can share with you.

Have you been able to discuss the symptoms with your doctor?
