CHQ: SUBJECT: Shortness of breath in the mornings
  MESSAGE: My wife has been having shortness of breath in the mornings (mornings only).  She has, what I think, excessive heart rate as well.  Again, mornings only. Could this be anxiety attacks?  I don't think it would be a heart issue.  She certainly isn't overweight.  SHe is 5'2" and 100-105 pounds.  if she is having anxiety attack... what is the best course of action?  She seems to feel better when she lies down and rests.....while either watching TV...or sleeps.  WHat is weird about it is ... it only happens in the mornings.  SHe has no history in her family for heart disease either.  WHat are your thoughts?
