Hello! I'm peturbed by heavy heartbeats at night. This began approx. two weeks after an argument with some builders who had done shoddy work at my house. During the argument I was struggling to keep calm but inside I wanted to smash them in. Because of this inner conflict I could feel my heart pounding at the time. It seems a bit of a delayed reaction I know, but for two weeks after the argument I had insomnia, and then this led to me waking up after bad vivid dreams with a racing heart beat.
This has gone on now for six months. Sometimes I can feel my heart beginning to pound at 8 pm, then I know it will be hard to rest that night. Usually it has settled by 5am, after which I can relax a bit. I have been to see my G.P. sometimes in quite a state. They have checked my bloods, B.P., ECG and found nothing, but put me on Ateno

. A Cardiologist arranged a 24hr ECG and this came back normal. Still, I cannot shake the feeling that my heart is now 'damaged', that night time is dangerous and that I cannot return to doing normal activities without undue caution.
Has anyone else felt trapped like this?
