I am 36 and I have been fighting with symptoms for nearly 3 years now that my GP and cardiologist diagnosis as anxiety. I have had the basic blood tests an ekg and a 24hr holter monitor which all came up normal. The holter was of course on a good day had no significant palpations... MY BP is often above normal at 135/90 been working to get it lower... I admit there is some anxiety however I feel that I would not have anxiety if I did not have these symptoms that make me feel like something is wrong with me...

I feel skipped beats often thru the day mostly in my throat. I sometimes confirm the skip in my pulse (as when I get one another usually comes shortly after). I had a sinus cold recently and used Claritin D and had multiple STRONG palpitations and now will have to obviously stay away from that. Whenever sitting still like watching TV, at a computer or lying down I can always feel my heart beating in my throat. Sometimes I can even see beats in my chest/stomach... I also have the need urge to take full deep breaths often, often wake up a bit sweaty/hot at night.

My question is should I demand some type on imaging (x-ray, echo, CT Scan) other than the holter and ekg's I have had? Maybe I am just hypersensitive now but I don't understand why I always feel my heart beating and didn't before and the palpitations are scary. I feel like just because of my age Doctors do not push extensive testing as the age/risk factor is low. Do I just trust my Doctors and try anxiety meds or push for more testing second/third opinion?
