abnormally pounding heart

[Rob2008]

Hello.   I'm a 30 year old male with a history of fibrous dysplasia of the skull and intractable headache,  but no other conditions.     In the last 4 years since my headache symptoms increased,  I've been not doing too much physically...In my early 20's I was skinny and active but in the last 3 years I gained 70 pounds from all the rest,   but I do still get up on the exercise bike 2-3 days a week.      Why am I posting a cardiac question,   well  lately it seems like my heart starts pounding very hard in my chest,  I will be mildly tachycardic (maybe 100-110) for several hours at a time,  and if I do something physical such as walk up stairs when I'm having these symptoms,  my heart will pound *extremely hard* at stay at maybe 130 bpm for a while.   But a few hours later,  I sort of feel relief all of a sudden and my pulse is normal again.       Luckily for me, I live across the street from an emergency room so I just went over there one night at midnight when it started and they told me the EKG was totally normal but I just had some sinus tachycardia,   also about $2000 worth of labs were drawn including thyroid tests, and later I had an echocardiogram and chest xray...still normal.      Also,  I wore a monitor for 30 days,  still nothing but isolated early beats.    Could this simply be from my physical de-conditioning,    or what?    I also tend to feel very nauseated and bloated sometimes during this.

It is reassuring that all your heart tests are normal. A non heart related cause for your symptoms seems more likely

Curious, could something like your gall bladder or liver cause symptoms like this too, since I feel nauseated alot?
