George helped me understand the important of Sodium as well. Many low carb diets have you drinking a lot of water, which depletes MG, K and Sodium. It was the sodium that was getting me to have skipped beats.

Low carb diets, especially when going through the keto or fat adaptation stage can cause electrolyte disturbances. This is because of the natriuresis of fasting. In other words, fasting or very low carb diets, <30g carbs/day, can cause very sharp drops in insulin. High levels of insulin signal the kidney to retain sodium, so when insulin drops, it signals the kidney to excrete sodium. In addition, in the beginning of a keto phase, the body depletes the glycogen in the liver and in muscles. Each gram glycogen is associated with 3-4 grams of water. So there will be water urinated out, carrying electrolytes with it. This adaptation phase is (as I noted in my post above) a risk period for someone with afib tendencies. Most guides to keto adaptation will suggest adding in sodium, potassium & magnesium during this time. I think if someone with afib wants to keto adapt, they need to be aware of this and prepare for it. I would also suggest slowly lowering carbs rather than an abrupt drop (which is what I did, because it was all I knew 9.5 years ago).
As I mentioned, I think the study doesn't tell us anything. The food frequency questionnaire data are fairly useless as the main input. Also the cut point around 45% calories from carbs (which would be 900 calories from carbs/day on a 2000 calorie diet) is nowhere near the point where there are electrolyte disturbances (maybe by as much as 10x).
I happened to have been at a medical conference since Thursday. I asked two docs who have prescribed low carb diets in their practice about whether they saw this associate in their clinics. One doc was from the UK and has been prescribing low carb for 7 years. He said he did not see the association, but recommends electrolyte repletion for everyone he prescribes it to. Another doc from the US has been prescribing it for 15 years. He looked at me and said, no, I treat afib with it!. This makes sense, as many presenting with afib have metabolic illness and there are data I've seen suggesting that fixing the metabolic illness can help the afib.

The Hunzas live a robust life past 100 years, they don't eat a keto diet, they do a little fasting and don't overeat, they eat a lot of veggies, yogurt, grains, nuts and a little meat.
