目的:探讨急性冠脉综合征患者合并室性心律失常与QT间期离散度的关系。方法:268例急性冠脉综合征患者将其分为室性心律失常组和无室性心律失常组,测定心电图QT间期离散度并计算校正的QT间期离散度,进行比较。结果:急性冠脉综合征患者室性心律失常组QT间期离散度与校正的QT间期离散度均明显高于无室性心律失常组(P<0.05)。结论:急性冠脉综合征发生室性心律失常与QT间期离散度有密切关系。
Objective: To investigate the relationship between ventricular arrhythmia and QT dispersion in patients with acute coronary syndrome. Methods: A total of 268 patients with acute coronary syndrome were divided into ventricular arrhythmia group and non-ventricular arrhythmia group. The QT interval dispersion was calculated and corrected QT interval dispersion was calculated and compared. Results: The QT dispersion and corrected QT dispersion in patients with acute coronary syndrome were significantly higher than those in non-ventricular arrhythmia group (P <0.05). Conclusion: Ventricular arrhythmia caused by acute coronary syndrome is closely related to QT dispersion.
