Which symptom is NOT associated with Wolf-Parkinson-White syndrome in children?

Wolf-Parkinson-White (WPW) syndrome is characterized by an abnormal conduction pathway in the heart, leading to episodes of rapid heart rate (tachycardia). Common symptoms associated with WPW syndrome include palpitations, which result from the rapid heart rates, sudden onset of pallor due to reduced cardiac output during these episodes, and difficulty breathing that may occur as a result of compromised cardiac function or anxiety related to the palpitations.

Persistent fever is not a symptom associated with WPW syndrome. It is usually related to infectious processes or inflammatory conditions rather than cardiac arrhythmias. In the context of WPW, the presence of fever is not typical, and it suggests a different underlying issue rather than an electrical abnormality in the heart. Understanding the primary manifestations of WPW helps clarify why fever, which indicates an infection or inflammation, does not belong to the classic symptomatology of this syndrome.
