Thank you for your query.
The EKG report is within normal limits. However the heart rate
of 128 per minute is high. Seeing your daughter's history and the complaints mentioned by you I am of the opinion that the cardiologist would ask for an echocardiography
to know the status of the heart and then order subsequent investigations to know the reason why your daughter is having the complaints that you have mentioned.
I hope I have answered your query to your satisfaction.
Wishing your daughter all the best..
