急性脑中风与QT离散度的临床分析

Clinical analysis on QT dispersion and acute cerebral stroke

目的:探讨急性脑中风患者QT离散度(QTd)的变化及其临床意义。方法:选择急性脑中风患者93例,其中脑出血48例,脑梗死45例,诊断主要依据CT检查予以确定,选择相应对照组。做标准12导联心电图,计算QTd。结果:与对照组比较,脑梗死组和脑出血组QTd增加明显,P<0.01,差异有统计学意义,但脑梗死组和脑出血组之间QTd无差异;死亡组与存活组比较,QTd明显增大,P<0.01差异有统计学意义;存活组治疗后QTd显著减小。结论:急性脑中风患者并发心电图异常,QTd显著增大。QTd检测有助于对脑中风的了解,防治各类心律失常的发生,以减少心脏并发症,提高救治效果。

Objective To investigate the clinical features of QT dispersion in acute cerebral stroke.Method Total 93 patients with acute stroke,including 48 cases of cerebral hemorrhage and 45 cases of cerebral infarction,received CT examination to be determined with appropriate control group.The changes of their QT dispersion were measured with standard 12-lead electrocardiography.Results Compared with the control group,QTd was significantly increased in cerebral infarction and cerebral hemorrhage group（P〈0.01）.The latter two groups had no difference in QTd.QTd of the death group was higher compared with the survival group（P〈0.01）.QTd of the survival group was significantly reduced after treatment.Conclusion QTd is significantly increased in acute stroke patients with complicated abnormal electrocardiogram.In order to reduce cardiac complications,QTd is helpful to the understanding of cerebral stroke,preventing the occurrence of various types of arrhythmia and improving treatment results.
