[Karin Jonczak]

Any history of asthma, or has anyone checked her tidal volume (Tv) (how much air is moving in and out of her lungs?)

Consistent low Tv can cause increased HR etc.... worth a look into at least. Either way, if she thinks something is wrong (and it really sounds like it is) she needs to find another doctor. In the long run it may have to remain 'cause unknown', but you should not be blown off like that (at least thats my 2 cents!)

Good luck,

Karin
