[|Human|] My son is 15 years old, and a few days ago he felt his heart beating faster and harder, along with some back pain and shoulder pain. His shoulder and back are fine right now, and his heart is going at a normal rate but he says he can feel his heart bumping hard, what is the problem?
[|AI|]  Hello! Welcome on Chat Doctor! I understand your concern and would explain that his symptoms may be related to anxiety. Anyway, I would recommend performing some tests to exclude other possible disorders like cardiac arrhythmia, thyroid dysfunction, an infection, etc. Besides a careful physical exam some tests need to be done: -resting ECG-chest X-ray study -lab blood tests (complete blood count, thyroid hormone levels, blood electrolytes, kidney and liver function tests, PCR, sedimentation rate). If the palpitations persist, an ambulatory 24-48 hours ECG monitoring would be necessary to exclude possible cardiac arrhythmia. Hope you will find this answer helpful! Kind regards,
