A fib and diabetes insidpidus

[mbb1]

I have been diagnosed with a fib, several years ago and am taking meds (beta blocker and antiarrhythmic, coumadin) I had a PVI 18 months ago and initially the frqency and duration of episodes diminished but never disappeared. recently, I was diagnosed with diabetes insipidus and have a fib episodes of increasing frequency (almost daily0 and duration (3-8 hours). Can there be a relationship between the tow (a fib and diabetes insipidus?) I am 50 years old and otherwise healthy, exercise regularly, eat well. Any info out there? MBB1

Diabetes insipidus can cause dehydration and electrolyte imbalances. Proper electrolyte balance is important to nerve and muscle (for instance cardiac muscle)  function. I got  AF in 2010, when I was dehydrated due to warm weather and had not drunk enough water. I have diagnosed that I have periods of mild diabetes insipidus (may make me apt to AF). During such periods I have polyuria, high serum osmolality and high serum Na+. My antidiuretic hormone decreses during water deprivation, although it should instead increase.  Doctors do not agree that I have DI.
