Firstly, I feel your daughter needs evaluation for a high resting heart beat, which should include an ecg as well as thyroid
hormone levels. So please ask her to see a doctor and get these tests done. Secondly, please also tell her that smoking
when on birth control pills increases her risk of developing blood clots
, stroke and heart attack
. So she should seriously consider quitting smoking or at least using other methods of contraception
. However, her present problem of a high resting heart beat is unlikely to be due to smoking alone and therefore, warrants a complete check-up.
Hope this has been of help. Best wishes.
