I have had 2 Aortic valve replacements, currently have titanium valve replaced in 2009. I have been experiencing strange triple heart beats for a couple years now, cardiac dr, has done lots of tests and says heart is functioning very well, no blocks, etc. a few PVCs, is all they have caught on holter 2 times, but i feel it all day everyday, sometimes worse than others a lot of times pre menstraul I get worse heart symptoms, I have recengtly this week been put of progesterone to see if maybe it is a hormonal thnig since the test results came back all messed up.I am a 42 year old female...However so far not helping but its only been a week, I am on BP meds and beta blocker , also bllod thinner. Should I insist I get an electro physiologist to look into things or believe my dr and let it go, because I am still totally focused on this, I have 2 children, 9 and 22, yrs old and they need me, THX for your help
