has anyone had heart palpitations? I've got a small hole in my heart, I've been for a scan on that about a month ago, but on Thursday and yesterday my heart beat really fast hard and unusual, enough so that it's kinda scared me a little. I'm off to the drs at 12 (so probable will be seen about 1.30 😕 haha) but I hate going - they make you feel like you're wasting their time. I've done a bit of googling and it says it's normal.....I don't like it.
