Yes fraz I know a lot of people aren’t at the stage of cardio, but here’s a thought. Ur heart follows a track electrically. Imagine it’s a figure eight. Every now and then, the heart for whatever reason might skip the figure eight and just do the loop. If the problem is electric, which in the case of afib it is, we might “miss the track” hundreds of times a day. Over time, because the new loop is worn in, this becomes the new electric track our heart rate takes, which is definitely not good. By excercising, getting ur heart rate up even with a walk, ur heart will pump hard and strong. I never feel afib when I’m excercising, even just a walk. So by doing this I’m forcing my heart to take the correct path, wearing the original track back in.
Also, I agree with vitamin b advice, but they can be extremely activating in wd. I could never tolerate them, and I’m still too scared to try x
But everyone is different 👍🏼
