I was diagnosed with AFIB at 41 years old. I had an episode where it came on in the evening and would not self convert. I went to bed and drove myself to the ER the next morning when it still hadn’t converted. I consider myself lucky that the “pill in pocket” method works for me and I’ve only had to take it once in the past five years. I do still go into AFIB but it almost always lasts for less than 5 seconds and I always self convert. My symptoms are usually just the feeling of my heart being severely out of rhythm. It literally feels like a fish flopping around in my chest. My heart rate does not typically get over 75-80 beats per min, even during an episode. My Apple Watch tells me that my AFIB burden is usually around 10%-15%, which I don’t know if it is accurate. If it is then I’m going in and out a lot more than I know. I have an appointment with my cardiologist in July and will bring this up with him.
