遗传性心律失常是一种与心脏电生理功能紊乱相关的遗传性心脏病,多呈常染色体显性遗传,大部分与离子通道基因突变相关,常发生于心脏结构功能正常的年轻人群。遗传性心律失常主要包括长QT综合征(long QT syndrome,LQTS)、儿茶酚胺敏感性室性心动过速(catecholaminergic polymorphic ventricular tachycardia,CPVT)和Brugada综合征 Hereditary arrhythmia is a genetic heart disease associated with cardiac electrophysiological disorders, mostly autosomal dominant inheritance, mostly associated with ion channel gene mutations, often occurs in young people with normal cardiac structure and function. Hereditary arrhythmias mainly include long QT syndrome (LQTS), catecholaminergic polymorphic ventricular tachycardia (CPVT) and Brugada syndrome
