What Causes Heart Palpitations In A Child?

I think, it's sufficient to rule out heart disease.
Detailed Answer:
Hello,
I think there is no need of further test.
Now, these symptoms raise the possibility of heart disease, but are not specific of heart disease in children. They can be present in otherwise normal babies. Normal echo will rule out heart disease, because by these symptoms we suspect congenital structural heart disease, not any arrhythmia, which can be ruled out by normal echo. ECG during breast feeding, means baby is having abnormalities in heart rhythm which occurs only during breast feeding, which we are not really suspecting in the baby. Normally also heart rate may rise to some extent in baby. In age group, 6-12 months heart rate is between 80-140 per minute. Avoid formula milk that contains Omega 3, 6, 9 as it may also have side effects.
If problem is significant, you can get baby examined once from local pediatrician.
Hope it helps. Let me know if I can assist you further.


She should get oxygen saturation and possibly repeat echo.
Detailed Answer:
ya, 193 is rare to reach in this age group.
First your doubts of ecg during feeding, since heart rate rises only during feeling that means it's not arrhythmia, but it's a sinus tachycardia so ecg will not provide any new information other that what we get on manual counting, however it will help to confirm the high rate.
Secondly, regarding alternative tests, best test to confirm congenital heart disease is catheterization studies, however these tests are invasive and not indicated at this stage. Instead i would advise you to buy one pulse oximeter device and you need to put it on child's finger, which will give childs oxygen level and pulse rate. So in that if oxygen level is low and pulse is high, then we will go ahead with more test.
Considering the echo was normal, we should suspect other problem like respiratory illness which can also cause similar symptoms.
In a nutshell, checking oxygen level, reconfirming high pulse rate, probably a repeat echo as sometimes some minor things could be missed on echo if not suspected, ruling out respiratory problems with the help of pediatrician will be a appropriate next steps.
