You need to quantify your palpitation and rapid HR condition for me to have any way to relate.  

It appears you doctor doesn't see anything wrong with either of the above symptoms, and thinks the details of the echocardiogram just need to be watched to see if any condition is getting worse.

All my echocardiograms and other detailed heart work/testing has been under the supervision of my cardiologist.  I guess it is better to see a specialist if you are not now doing so.
