Please follow up with your Pediatrician. If there is dizziness, shortness of breath or change in coloration, go to the emergency room. There may be a need for dose adjustment nas she gains weight. Keep her well hydrated, monitor temperature. A virtual consult with Healthtap is available.

"Heart racing constantly" does not describe the problem adequately. You have not provided your daughter's age, but taking a beta blocker without a clear indication is not wise. Please discuss this with the doctor, express your concerns, and raise the question of a second opinion if your daughter has no established indication for a beta blocker.
