I have HOCM and afib and Mg and potassium helps wonder with the extrasystoles. I also take taurine against the extrasystoles in combination with Mg and K in the evening before going to bed and I can sleep much better.
Yeah, I didn't go into the whole spiel as off-topic (and this comment isn't the whole spiel, either...), but taurine for heart issues seems like something that should just be tried by almost anyone experiencing them. It has basically no overdose risk, as it's an amino acid everybody consumes anyhow, and there are many papers showing it can help. So, very cheap, basically no downside, possible significant upside, abundant scientific support. It was one of the first things I tried that had an immediate, positive effect.
Digging into this sort of thing did convince me there's a lot of truth in the idea that you can't get the medical world very interested in solutions that don't come with a patentable treatment. There's a lot of papers I've found about how much heart stuff can be treated by correcting various deficiencies, such as taurine, or magnesium & potassium, but it all seems very under-utilized by the medical community themselves.
(Incidentally, just as that abstract says, the literature suggest adding L-Arginine to your taurine may also be beneficial as they work together. If you're fine now, I wouldn't suggest rocking the boat, but if it's only 80-90% effective or something, you may want to consider adding that as there's a decent chance it could take you to 100%.)
