I've been having mild chest pain, palpitations that make me dizzy for quite some time. I was referred to the hospital and the consultant ordered tests. I had a 24 hour heart monitor, heart scan and treadmill test. They haven't found anything to cause concern and have discharged me back to my gp. I'm at my whits end with it all. My symptoms are worse, I can't even lay down to sleep as it feels like my heart goes into a weird rhythm. Some advice would be great. I have no stress or anything.x
