Then of course the is cardiac problems such as svt, vetricular tachycardia
Problem with tachycardia in babies is that is hard to detect unless patient is on monitor most signs will be not specific such as not eating irritable
Treatment depends on underlying cause
It can be:
1.physiologic (meaning normal) response of the heart to some situations
( like fever, anemia, infection, certain drugs or medication....)
2. due to a dysrythmia ( abnormality of the cardiac rythm )
In all cases tachycardia may be dangerous depending on its cause, a pediatrician and in some situations a pediatric cardiologist must be consulted to decide of follow up and treatment when needed.
