I've had two AFIBs. In June of 2022 & 2023. The first one just felt like a hollow feeling in my chest. At age 76 I thought I should be careful and go to the ER. After being there a bit the ER Doc said, "You came here with an AFIB and stopped it in 8 minutes. How'd you do that?" I told him that I just went into my Yoga/Navy
Seal breathing technique. Later I saw online that this breathing technique is one of the things that can help. The other is exercise. This is what I saw on the web not my medical advice. The second one was more typically the heart out of rhythm. On that occasion they gave me Diltiazem IV to resolve the issue and kept me there for 3 nights. This was because they put me through every test there is. I did well on all of them. But, now I have a Cardiologist that I see every 6 months. I have not had a recurrence. I am on Diltiazem and Eliquis daily. I have no side effects and do whatever I want. I am now 79. I go to the gym and lift 4 times a week. I have been off the bike all season but that was because I had inguinal hernia surgery. But, I just did a 3-day motorcycle trip on my Triumph Street Triple with my moto group. I offer this as an example of what is possible. If I were you I'd talk to a Cardiologist about exercise and other treatment options. Best of luck.
