In another thread Jackie mentioned these conditions. It would seem important for anyone with AF to have the possibility checked out by a competent nephrologist:
What is Bartters Syndrome?
Bartters Syndrome is an inherited defect in the renal tubules that causes low potassium levels, low chloride levels, which in turn causes metabolic alkalosis. Bartter Syndrome, is not a single disorder but rather a set of closely related disorders. These Bartter-like syndromes share many of the same physiologic derangements, but differ with regard to the age of onset, the presenting symptoms, the magnitude of urinary potassium (K) and prostaglandin excretion, and the extent of urinary calcium excretion.

What is Gitelmans Syndrome?
Gitelmans syndrome is a rare inherited defect in the renal tubule of the kidneys. This defect causes the kidney to waste magnesium, sodium, potassium and chloride in the urine, instead of reabsorbing it back into the bloodstream. Urine calcium levels are lower than normal, despite normal serum values. This syndrome does not cause kidney failure nor does it cause the kidneys to function abnormally. The kidneys are normal. The problem is the reabsorption of important electrolytes and minerals.
