To the Editor: Catecholaminergic polymorphic ventricular tachycardia (CPVT) often occurs in children or adolescents without organic heart diseases. It is a rare malignant arrhythmic disorder with hereditary features characterized by exercise? or emotional stress?induced ventricular arrhythmias, especially bidirectional/polymorphic ventricular tachycardia (VT), syncope, or sudden death.[1] The mortality rate of symptomatic CPVT patients before 30 years of age is 31％,[2] and an early treatment with beta?blockers could effectively improve their prognosis.[3] Therefore, getting a confirmed diagnosis of CPVT in time is of utmost importance. On this context, this study summarizes the clinical characteristics and diagnosis of pediatric cases with CPVT. This study was approved by the Ethics Committee of The First Hospital of Tsinghua University (No. HX200901) and was conducted in accordance with the 1964 Declaration of Helsinki.
