Hello, After going through the medical details I understand your concern for your daughter’s health and I would like to tell you that most common reason for chest pain or palpitations in children is stresses, anxiety like you said she is facing stress in work and her sports. But even then cardiac evaluation is required to exclude any underlying cardiac disease. Kindly get an ECG and Echocardiography done to evaluate if any heart disease is underlying and consult with a psychologist for counselling if she is too much stressed. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Bhanu Partap
