摘　　要：目的了解自发Ⅰ型Brugada波患者的QT间期及QT间期离散度变化的意义。方法对15例自发Ⅰ型Brugada波患者进行12导联心电图检测,描记12导联同步心电图,测量QT间期,QT离散度,比较呈典型Ⅰ型Brugada波与无Brugada波之间的差异及对照组之间的差异。结果患者自发Ⅰ型Brugada波时,QT间期,QT离散度,与无Brugada波时有显著性差异,P<0.05。对照组为身体健康者同年龄组15例,各指标与Brugada组有显著性差异,P<0.05。结论患者自发Ⅰ型Brugada波时,QT间期,QT离散度,可明显高于无Brugada波时及对照组,猝死的风险明显增加。Objective To explore the spontaneous type 1 Brugada waves in patients. significance of QT interval and QT dispersion changes in Methods Fifteen patients with Spontaneous type I Brugada waves were directly examined with 12 lead electrocardiogram, QT interval, QT dispersion was measured, type I Brugada waves were compared with non-Brugada waves and Healthy control group. Results The QT interval and QT dispersion in spontaneous type 1 Brugada waves are significant difference to nonBrugada waves ,P 〈0.05; compared with Healthy control group（ 15 cases ）of the same age ,each index is significant difference, P 〈 0.05. Conclusion In patients showed in spontaneous type 1 Brugada waves the QT interval, QT dispersion probably are significantly higher than non-Brugada waves and the control group ,patients showed spontaneous type 1 Brugada waves is not only the early repolarization abnormalities, but also the repolarization time and its dispersion increased significantly and increased the risk of sudden death.
