Phil, I was the one with the scattered discussion about temperature 
regulation.  It was almost prescient.  With very little exposure to heat, I 
felt extremely bad on a Thursday.  Friday I walked in a mall but zero 
exposure.  Saturday I got my forth bout of Tachycardia - this time while 
taking Digitalis.  It is such an odd thing to just be sitting somewhere - not 
upset or anything and wham the pulse hits 220.  Another ER visit and 
Adenosine.  This is getting very old.  I guess this time I have questions - 
could the Thursday problem and discomfort I was feeling for a couple days 
have something to do with the Tachycardia?  I had the heat exposure on a 
Thursday could it cause problems on a Saturday.  I'm kind of new to a 
diagnosis of this stuff and I'm only 41.  also, Magnesium like 1.8 just 
barely normal - possible effect?  And high antibodies to thyroid but TSH 
inching up T4 inching down but still normal (TSH 4.2  T4 6.0) a thyroid 
effect?  Thanks - maybe if we leave all the political stuff alone - don't 
answer it and ask more medical questions this echo can get back on topic- 
Grand Rounds is a name more for diagnosis than other stuff.  Cathy.
