I am sure many suffer from heart Palpitations during or after cycles. I have been recently experiencing some and did some research here are my findings.

Racing heart means not enough cortisol, salt and fluid volume. One without the other two does not work. I was told that I had anxiety/Stress and the presenting symptom was a racing heart with some Anxiety medication thrown in for good measure (Does not work). The best that could be done for me was heavy doses of beta blocker drugs. I refuse to take beta blocker drugs the sides are horrible.

The research shows DHT reduces Cortisol and that when Adrenals may produce Catecholamines, these are hormones produced by the adrenal glands, which are found on top of the kidneys. They are released into the blood during times of physical or emotional stress. The major catecholamines are dopamine, norepinephrine, and epinephrine (which used to be called adrenalin).

Only Blood work can show which,Thyroids or Adrenals can cause this but when you run your blood test make sure to ask your doctor to Check your THS along with T3 and T4 levels not just THS.
T3 or T4 level will show which many have caused this Thyroids or Adrenalins. Here is how to check your adrenalin http://www.nlm.nih.gov/medlineplus/ency/article/003561.htm

Adrenals before thyroid always for insufficiency/low adrenal reserve or you could risk an adrenal crisis. The palpatations etc sound like an adverse effect to the drugs, I am saying Taking time off and getting started again with sorting your cortisol out will get you on your way

Isocort OTC providing 2.5MG natural cortisol in each pellet or Prescription Hydrocortisone will get you on your way, and this how adrenals and Thyroids fuck you up! http://www.iherb.com/product-reviews/bezwecken-inc-isocort-adrenal-suppo...

Hope this helped it cleared some of the stuff that these Dumb doctors could not.
