In this article, we present a 10-year-old boy who was admitted to the hospital with recurrent syncope. There was no remarkable finding in patient’s physical examination, family history, and the diagnostic 12-lead electrocardiogram (ECG), chest x-ray, ECG Holter monitoring, event recording, echocardiography, coronary computed tomography (CT) angiography, Ajmaline test for the diagnosis of Brugada syndrome, brain magnetic resonance imaging, and sleep/wake electroencephalogram. We started beta-blocker therapy because the patient had exercise-induced syncope. An Implantable loop recorder (ILR) was inserted to the patient. Three years later, polymorphic ventricular tachycardia called torsades de pointes was detected by the ILR during syncope occurred with exercise. The patient had been taking high-dose betablocker treatment, an implantable cardioverter defibrillator was implanted into the patient. ILR can play an important role in the diagnosis of life-threatening arrhythmia in children with unexplained syncope.
