Brenda, a tip:
Many with heart rhythm disturbances reduce and even eliminate most of 
them by "supplementing" their diet with potassium gluconate (powder, NOW 
brand), magnesium chelate (Albion process), and taurine - the big three. 
These people are all carbohydrate eaters, many of them "modified" paleo 
AKA cheaters.
Zero carb/pemmican eaters don't supplement them because they are all 
present in balanced form in raw meat, and bio-available IN THE ABSENCE 
OF CARBOHYDRATES.

I've tested a supplement on myself and found that I have a 
potassium-wasting body; this is an [b]inevitable[/b] part of 
carbohydrate metabolism. For me, as I have psvt, and it is caused by 
deficiency - mostly potassium.

AFAIK you are probably in the same boat. The only way I know to prove it 
is to test the proposition by doing a pemmican-only diet, which is after 
all the strictest paleo diet.
