摘　　要：目的:探讨自主心律控制和QT间期变异对Ⅰ型长QT综合征(long QT syndrome,LQTS)发生心律失常风险的影响。方法:通过对就诊于海口市人民医院心内科的LQTS患者和非LQTS患者进行病例对照研究,确定LQTS发生的主要危险因素;再通过LQTS患者的分型对不同型别的LQTS患者作对照研究,确定自主心律控制和QT间期变异对Ⅰ型LQTS发生心律失常风险的影响。结果:LQTS发生的主要危险因素包括男性、晕厥病史、QT间期>500ms。Logistics研究发现,发生自主心律控制和QT间期变异患者发生心律失常风险的危险性增高。结论:自主心律控制和QT间期变异可以增高Ⅰ型LQTS发生心律失常的风险性。Objective：To discuss the influence of the autonomous control of rhythm and the QT interval variability on the type I long QT syndrome（LQTS）. Method：We collected the patients with LQTS or non LQTS in Department of Cardiology, Haikou Municipal People ＇s Hospital, and identify the main risk factors for LQTS. Result： The main risk factors of the LQTS included male, syncope, QTc longer than 500 ms. Patients with Type LQTS had been more liable to develop arrhythmia when the autonomous control of rhythm and QT interval variability occurred. Conclusion： Autonomous control of rhythm and the QT interval variations increase the arrhythmia risk of type I LQTS.
