I have 18 year old son. He says his heart races about 5-10 times per day, blood pressure off and on can be higher and if exert self he says can race.  I took him off all caffeine but still happening.  Has had blood and urine test, and had ultrasound of heart that sows nothing.  What should I do next
Answer: Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I think he should get his thyroid function tests (TFT) done first. If TFT is normal and the symptoms occur on daily basis a 24 hour Holder monitoring will tell us whether the palpitations are benign or needs some treatment with medicines. Hope to have been helpful! Wishing all the best,
