Hi! I've been where you are now, and it is scary. I was diagnosed with tachycardia and pvcs which always got worse before and during my period, at times they were almost non-stop. I went on a low-dose birth control pill 2 months ago and it has made all the difference in the world, not only with my heart but with everything else also! I was absolutely miserable--unable to sleep, mood swings like crazy, night sweats to the point where I would have to change sheets, and on and on. I recommend a great book by Elizabeth Vleit, MD, called "Screaming to be Heard: Hormone Connections that Women Suspect and Doctors Still Ignore". It covers the heart (and everything else) extensively. It answered questions that I didn't even think to ask! And it gave me lots of information to knowledgebly talk to my dr. and decide which was the best course of action to take for me. I ordered it from ******, it arrived in 2 days and helped save my life and my sanity (and my hubby's!). Take care and if you decide to get it please let me know how you like it. Thinking of you, Cat
