Hello, since the complaint has now lasted for almost, it would be appropriate to get an ECHO done for your child to lay all the speculations to rest. Palpitations commonly occur due to anxiety
, drugs or an underlying heart problem. It is important to rule out any stress
which your child might suffer at school or elsewhere. Does she have similar complaints at night ? Does she get a disturbed sleep ? So to sum it up, identify any stressors before you proceed further.
