Hey,  Doc!? Do you have any cite(s) for that?? I would love to show it/them 
to some  of the smarmy docs around here for whom (like those everywhere else, I 
 suppose) lab #'s are the gold standard.   >>>>
Sure. Look in Braverman's textbook under Hypothyroidism and Psychiatric  
Disorders. That chapter says something like: Although Depression and Lethargy  are 
common presentations of Hypothyroidism; Insomnia, Anxiety, and frank Mania  
have been reported. 
 
Braverman's 6th edition had a lot on the Deiodinases, but I don't recall if  
that author talked about their being activated by low T3 in circulation. 
 
I had read about the mechanism in a Psych book or article that said that  low 
T3 in the blood activates the Deiodinases in the brain.
 
The heart thing, I learned when I told Ken Blanchard that my sister was  
Clinically Hypothyroid; but she had Atrial Fibrillation which I always  associated 
with Hyperthyroidism.
 
He explained that Atrial Fibrillation is not rare in Hypothyroidism because  
of activation of the Cardiac Deiodinases, and I was impressed that the  
mechanism was similar to the brain mechanism. 
 
I learned a long time ago, it pays to hang out with people who know more  
about something than I do....
