I have AFIB off and on now for decades. If you had only one probably something your doctors want to monitor. When you said converted with medication. Where you referencing Eliquis or something else. Eliquis is a blood thinner.

You are right that the most concern by cardiologist (per my Mayo cardiologist and EP) is if you have sustained AFIB is can cause a stroke. But you have only had one episode. You did a 2 week Holter monitor and appears this was an isolated event.

Being under stress and anxiety per my EP can cause PACs and PVCs which can move into AFIB and VFIB and you need to address the anxiety. Medications can help but changing lifestyle can really help. Do you like doing any type of exercise? How about a hobby. If you have an exercise you like doing check with your doctors and try to do it. Exercise is going to help you both mentally and physically. Do a hobby is going to relax you.

How is your weight? Can weight affect AFIB? Per my Mayo EP yes, as well as PVCs, and PACs.

Talk to your doctors about your concerns. Are you seeing a electrophysiologist (EP) they are cardiologist specialty trained in electrical functions of heart. But from my experience with my EP (now over 20 years) seems they did the right tests and trying to assure you isolated event but occurs again will address.

You mentioned Chads Score. Is that the test done to determine impact on heart or something else.

Sometimes per my EP AFIB is an isolated event. My EP states it is the continuous one that starts to affect the function of heart that they are most concerned with.

To answer your question: No, I did have AFIB sustained back in 2006 but corrected itself like yours and was not put on blood thinners. I have isolated episodes like yours since then had what the call non sustained AFIB that corrects itself.
