Hi blu78 and welcome!
I am sorry to hear that you are experiencing the palpitations currently.
This is a common anxiety symptom...and one that is hard to deal with, due to the discomfort and worry they cause.
It is good that you are seeing a cardiologist, so as to rule out any issue that needs to be addressed...
...however, I am pretty confident that you are going to find all is well, and learning coping skills and acceptance of this effect of anxiety will be your next step.
Have you done, or considered therapy...self-help? Both of these treatment options along with the Rx you have can really be a great combination in keeping anxiety levels as low as possible.
I am posting some links below...as well as inviting you to view our entire Resources at the top of the main forum page...
