Thanks so much everyone for all your replies, it has been very interesting reading how many other ladies get the same symptoms with their heart and are told by doctors that it is just anxiety! I have been to the doctors quite a few times over the last few years with my horrible racing heart symptoms at night and everytime they just say that it is probably just anxiety because my FSH tests were normal! However, I know this is not normal for me, I slept like a log before that rapid heart beat episode 2010! It was so frightening that I had what I think was a 'nervous breakdown' with panic attacks night and day and not being able to go out of the house without fear of getting a panic attack somewhere. I've still got bad anxiety now, so does that mean I've still got a nervous breakdown or is it my bloomin' hormones?!
The thing I fear most is the rapid heart beat episodes where I wake up suddenly, my heart does a huge lurch and then beats really rapidly for about 2 mins and then eventually calms down. During that time I feel really weird and feel like a might faint - it is the scariest thing I've ever experienced! Everytime it happens I think I'm going to get a cardiac arrest and wonder whether I should call 999! However, recently it just seems to be the pounding heart not the really rapid one which I dread.
I had no idea that perimeno could affect the heart like this and it completely took me by surprise - hence the nervous breakdown! I do still have a heart health anxiety though and spend quite a lot of time during the day and at night feeling my pulse to make sure it is regular because I hate the feeling of my heart pounding and as for missed beats omg - I hate those with a passion! I never had palpitations before I tured 39 so I'm convinced it is hormones not just anxiety! I'm fed up with going to the doctors and just being told that I should go and have some more CBT. What was happening to me at night caused the anxiety in the first place - chicken or egg!!
I'm so glad to have found this forum where there are so many lovely ladies offering help and support. I talk to my husband about it and my mum knows about it and keeps saying it is my hormones but it is the sort of thing you keep to yourself and suffer in silence. If it is perimeno, I don't like it one little bit and I keep wishing it would go away and I could just go back to feeling like myself again.
