Talk with your Doctor and ask if you should be taking anything. When I was diagnosed with paroxysmal AFIB in 2019 I had a Rapid Ventricular Response (RVR) and heart rate was at 165. I had two incidents like this with 2 days of the first diagnosis. On the second time the ER doctor gave me a beta blocker. When I did follow-up with my Primary Care doctor, he prescribed a Beta Blocker and Eliquis. I was doing great for about 2 years, and I had another event and they had me do a nuclear stress test. The results of that showed my heart was fine. Sent home with same medications. Two years later I had a tooth infection that caused the heart to go into AFIB (RVR). At the ER they monitored it and noticed the heart was in Tachy-Brady syndrome. Once stabilized I was discharged. Within an hour of being home I went into AFIB (RVR) again and back to the ER. At this point the doctors called in the specialist (EP) that felt that the beta blocker wasn't the best choice and spent 5 days in the hospital with a new medication in the antiarrhythmic class (Dofetilide). This drug was focusing on the rhythm of my heart. Three months later they did an ablation and also measured the heart to see if I was a candidate for the Amulet or the Watchmen. Unfortunately, I wasn't a candidate for the occlusion device but so far, no more AFIB. I am off the Dofetilide and just taking Eliquis. The ablation happened in October 2023. So, to answer your question is if your heart isn't beating out of your chest which you will feel this, and it occasionally is out of rhythm then it doesn't sound like you need anything other than protection of a potential stroke (clots).

Now, it will depend on how often you have the AFIB. If you don't have it often then no you probably don't need anything else right now. Your doctor will prescribe what you need so discuss this with them!
