We're glad to hear that things are improving for you. Indeed, the condition is benign in all regards.

Now that you've established a sense of control over the frequency and or intensity of the palpitations, you will begin to have less and less symptoms. By doing so, you will have overcome the greatest hurdle in dealing with the condition, which is the realization that the symptoms are purely the consequence of anxiety and stress, subsequently controlled by establishing more rational thoughts. Your health is in no danger whatsoever.  

Best regards and Good Health
