First, a little background. About 8 months ago, I felt a fluttering in my chest. It lasted for a minute or two, and during this time I felt light headed (anxiety?) After this, I became more aware of palps(PVCs?) that I have been having most of my life. Had some pain on upper and lower left side and shoulder. Mostly 2" above nipple and maybe 1" toward center. Doctor took an ekg, which was normal(showed slight anbormal sinus rhythym...tach, I think). A week or two later, felt "pressure" and pain, ER took X-ray and ekg....normal. Finally, GP ordered 24 hour monitor and echo. The tech that did the echo said my heart looked "great" and that I had "great flow" During visits with two Drs, they reviewed echo and monitor reports. Both said that there was nothing abnormal or "life threatening" Was prescribed .5mg Xanax (I am under a HUGE amount of stress) Since then, palps come and go. Never more than 3/day One really hard beat that feels like my heart is coming out of my chest, then all is fine. The problem is now I am having these pains again. I have been really gassy lately (stress?) and when I drink something cold, I feel the cold go through the spots where I am having pains. My question is, could they be stress induced gastric probs, muscular tension, or should I get more tests on my heart? I should note that I do quite a bit of strenuous work with little or no shortness of breath, and no increase in pains or PVCs. Also, when not thinking about pain or doing something fun, I rarely if ever feel it. HR usally around 80, never more than 120. BP averages 125/75
