Thanks for the input cardiactec, our daughters peadiatrician with an 'interest' in cardiolagy has passed her back to her normal Pead. as he said her stress test was ok and her 24 hour holter monitor seems fine except for some flutters!! here and their, that he explained are like poeple get when they have too much coffee or such. Well bit odd too me as our daughter does not drink coffee, tea, coke etc. cos it makes her heart race. The 24 ECG was done on a good day with no real issues that day. I asked him if this could be an ANS thing and he said he did not know maybe I should could ask my sons neuro about it!!! I have requested a written report so I can take it to her GP to see what he thinks. Our daughter has EDS, so we thought it might be pooling issuses at work but she can get very bradycardic while sitting or lying, Dr.s just say she is young and fit she should be glad to have an athletic body but it makes her feel so out of it she says she hates felling so tierd and 'dippy' then when she stands too long her BP drops and her HR goes up and up, homones seem to play a big part in all this, she always has underline problems but it is much worse 2 weeks prier to her monthlys, or when she is ill etc. I think we need to find a Dr. that knows somthing about her electrical system!! Thanks again, Anna
