Hi, For about 2 weeks now my heart has been skipping beats from about 1-6 times and anywhere from 1 to 20 times a day, but only when i am up and moving around and sometimes sitting, i dont feel any when im laying down or when i ride my bike that i have just started to ride again, i also get chest pains that change in severity or none at all, sometimes when i have skipped beats i pull my shoulders back and they sometimes stop., i had some skipped beats about 6 months ago and they went away when i took magnesium, but it is not helping this time. About a year ago i had chest pains and light headedness and had a treadmill stress test done and everything was normal, all blood test were pretty normal except for some kidney function, chest x-ray and pulmonary test showed nothing, the pains eventually went away but the light headedness never really goes away ranging from not noticable to like being awake on Nyquil. Does anyone have a clue as to what may be going on with me? I have an appointment set up at the end of the week, but would be nice to know something now
