I have had an irregular heartbeat for as long as I can remember (I'm 54 now) and it gets worse with stress, alcohol consumption and exercise. When I jog at an easy pace on a treadmill my heart jumps all over the place, beats in my throat and generally I feel horrible. After 5 minutes, it calms down to a steady beat. On the days I run, which is around 4 per week, I am guaranteed to have a horrible night's sleep where I wake up thrashing around and sometimes this happens every time I fall asleep until I finally drop off. You can imagine that the next day I feel exhausted due to lack of decent rest. I have had many, many tests over the years including an angiogram last year and the results were 'normal' with no signs of heart disease or arterial problems. Does anyone else suffer from this condition and if so, is there anything which can be done to help? Thanks!
