I'm nearly 18 weeks with twins. Second pregnancy. A couple of weeks ago I had 50 min of palpitations with my heart rate of over 200, then another few hours of it being 110, then it calmed down and I felt normal again. I got seen urgently (obviously!) and was referred for an ECG and thyroid tests. Thyroid tests have come back normal, I have the ECG with me now to take to the GP which is happening tomorrow. I felt fine during the ECG but they didn't say anything about it, said the GP would talk to me. But over the last few weeks since the main episode I've now had more weird sensations in my heart, and now they are happening several times a day for anything from seconds to 10-15 minutes. DH (trained first aider) just took my pulse and it's 120 - that's quite high right? I'm starting to get really worried something is really wrong! I know I need to just wait until tomorrow when I see the GP but just wondered if anyone else had had something similar and what it turned out to be?
