Case Report: Fatal Ventricular Tachycardia Exacerbated by Fever in a Child

Primary ventricular tachycardia (VT) is rare in children. We report a child with VT exacerbated by fever which was ultimately fatal. His first episode occurred at 5 months old and recurred with fever, occasionally causing syncope. Episodes were difficult to control with antiarrhythmic agents during fever but remitted with antipyretics. He was admitted to hospital 23 times because of VT and died suddenly with fever when he was 17 years old. At autopsy, severe fatty replacement of the bundle of His and interstitial fibrosis of the sinus node was found.
