I'm 34 weeks and had palpitations over the last week. Pulse goes up to about 110-120 (recently my baseline has been 80-90, but pre-pregnancy pulse was around 60). Lasts anything from 30secs to a few hours. Sometimes it happens when I'm at rest, sometimes on exertion.
I've been checked out, ECG and most bloods normal. Thyroid blood tests still pending. Am booked for a 24 hour ECG and consultant follow up next week. Just wondered how common this is, as I've been told by lots of people this feeling can be normal in 3rd trimester. It doesn't feel normal when it happens though - it makes me feel really anxious and like I can't breathe.
