What Causes Rapid Pulsations And Heart Beat?

My 15 year old son has occasional fast heart beat with no physical activity. He has ADHD and takes Adderrall 20 mg./1 time a day. He s 5 5 & weighs approx. 110 lbs. I took him to a pediatrics cardiologist who listened to his heart & took an EKG. All normal but he prescribed him to wear a heart monitor for 1 month, but of course my teenage son thinks it s a nuisance & won t wear it now. This morning he comes into my room while he s getting ready for school and has me feel his chest. His heart was beating fast, almost like pulsating. He said he felt fine & had no shortness of breath. It went away within a minute or two. What can be causing this? I m worried yet he seems okay with it and doesn t want me to tell the doctor. I think he should have an ultrasound.

Cardiologist 's  Response
Hello,

I would agree with you on the fact that a cardiac ultrasound would give more information on his heart structure and function and exclude possible congenital heart defects.

I would also recommend checking his thyroid hormone levels for thyroid gland dysfunction and his blood electrolytes for possible imbalance.

A complete blood count should be checked too, in order to exclude possible anemia, which can trigger ectopic heartbeats.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
Dr. Ilir Sharka, Cardiologist
