What Causes A Fast Heart Beat?

My baby has a really fast heartbeat. They are sending us to a pediatric cardio dr. I am worried! I don t see any warning signs.... like blueness. What could be wrong? He is also not making lots of wet diapers. Could he be dehydrated? Would that cause a fast heart beat?

Hello dear,


You should be worried ,but not too much. Babies usually have high heart rate.
Infant-140-160
till 1_year-120
5years-100
Other possibilities:
- iron deficient anaemia, that's why perform blood test;
-congenital arrhythmia. ECG will rule off;
-lack of potassium.
If you have more questions I will happy to help you
Wish you and baby good health
