Hi, for the past 2 weeks ive been getting a fast heartbeat. Its worse at night & it's keeping me awake. I've been to my gp & have had bloods & ecg to rule out anaemia or thyroid prob, all tests were normal. It's settled during the day now but some nights it beats a bit too fast & i can feel it beating more. i think i may be getting anxious about it keeping me awake therefore im worrying about it. I cant seem to get it out of my mind when im trying to sleep. Thanks for your help.
