急性脑梗死患者的动态心电图异常

Abnormal dynamic electrocardiogram in patients with acute cerebral infarction

目的了解急性脑梗死患者心电图复极改变和心律失常情况及其与岛叶病变的关系。方法检测７４例急性脑梗死患者和３９例对照的２４小时动态心电图，分析其心电图复极改变和心律失常。结果右侧大脑半球岛叶梗死患者急性期室上性快速心律失常和房颤发生率明显增高；左侧大脑半球岛叶梗死患者急性期心电图ＳＴ段降低发生率明显增高。结论左侧和右侧大脑半球梗死对心脏的影响不同，岛叶病变在其中起着主要作用。

Objective To assess the effect of lesions of insular cortex on cardiac damages in patients with cerebral infarction. Methods 24 hour dynamic electrocardiogram recordings was measured were performed in 74 patients with hemispheric cerebral infarction in the acute phase and in 39 control subjects. Results Supraventricular arrhythmias were significantly increased in groups of right insular infarction as compared with groups of lesions in other regions and with the control. A significantly increased rate of ST segment abnormality was found in groups of left insular infarction as compared with groups of lesions in other regions and with the controls. Conclusion The effect of hemispheric cerebral infarction on heart function are mainly correlated with destruction of insular or regions adjacent to the insular. Increased rate of supraventricular arrhythmias is associated with right insular infarction. While increased rate of ST segment abnormality is associated with left insular infarction.
