Hi there Juliette,

Not sure if you are still reading this thread, but thought I would post a reply as I seem to be having a similar experience to you. I am not pregnant, but had my second bub 10 weeks ago. One week ago I suddenly started noticing my heart was skipping beats fairly frequently. They became worse over a few days so of course I panicked and ended up in Emergency. The ECG noted PVCs as well. Yesterday I had an echo and a halter monitor fitted - I get the results next week. Mine seem to get worse when sitting and lying down - going to bed is horrendous - all I want to do is sleep, but the constant flip flopping of my heart makes it impossible. I'm a bit of a basket case!! The anxiety it causes is amazing. I have done a fair amount of reading (the heart rhythm forum on medhelp is helpful) and in an otherwise healthy heart, it seems to be a benign condition that you just have to live with - I'm desperately hoping mine goes away when my hormones settle down but I'm aware that it may now be with me for life. Crazy - one day you are perfectly fine and the next it feels like your whole world has been turned upside down!!
Anyhoo, just wanted you to know you are not alone! I hope everything settles down for you after your bub is born - the added anxiety is SO not welcome!

Take care.
