[|Human|] My son doesn t drink beverages with caffeine or take medication. He is 14 and is a wrestler so he works out regularly. He is having heart palpations on and off lately. He is an anxious person by nature so he does have anxiety from time to time. He had an EKG, some blood test, a chest x-ray and the doctor listened to his heart. All tests were normal. He is convinced something is wrong and gets upset when he feels these palpatations - they are brief and he can have days without them and days with one or a few. I am taking him back to his pediatrician but wonder what other tests can be done to rule out a problem and put his mind at ease. Thank you.
[|AI|]  Hello, These symptoms could be related to anxiety. Anyway, I would recommend performing an ambulatory 24-48 hours ECG monitoring in order to examine his heart rhythm trends for a prolonged time and checking his thyroid hormone levels for possible thyroid gland dysfunction.  If the above tests result normal, you should consider anxiety as the main cause underlying his complaints.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
