Ventricular arrhythmia-induced syncope as the initial presentation of Wilson disease in a 4-year-old child: a rare...

This case illustrates a rare presentation of Wilson's disease, as ventricular arrhythmia-induced syncope was the initial and only manifestation in a young child before the development of classic hepatic or neurological signs. It underscores the importance of considering metabolic and genetic aetiologies in paediatric arrhythmias, especially when accompanied by abnormal liver function. Moreover, early recognition and initiation of chelation therapy can prevent disease progression and enable timely screening and management of affected family members.
