Tachycardia and electrolytes

What electrolyte imbalances can cause tachycardia?

Which electrolytes can improve tachycardia?

What is the best way to balance/replenish electrolytes without causing deficiencies?

Are there other causes/treatments for rapid heartbeat? (If there is another post where this is already answered can you please link me?)

I just found out my feeling my heart beat all the time was from low potassium. I started taking it when I started methylation and it made a huge difference. I used to take 30 mgs propranolol every night and now I'm taking 10 mgs and that's only because I didn't want to cold turkey.

When I feel it starting I grab 200 mgs potassium and I'm good.

I did try Nuun, which is an electrolyte balance but it didn't help like the potassium

And I don't have POTS. I just feel my heart beating all the time, annoying.

The potassium helped? Do you take any other electrolytes? Eg salt water, magnesium, calcium?
I have upped my potassium but it doesn't seem to be helping...

My fast heart rate to a large extent went away after I started drinking distilled water. I occasionally drink a bottle of gatoraid which doesn't seem to have any effect. I did switch to spring water for a short stint and none of my symptoms came back. So I suspect it's the tap & well water here in s central nm. Way too high in minerals and or poor combination of them.
