基底动脉尖综合症患者心电图缺血样改变及QT离散度与预后的关系

目的观察基底动脉尖综合症患者早期心电图缺血样改变及QT离散度与预后的关系。方法 63例基底动脉尖综合症患者入院后24h内常规描记12导联ECG,测量并计算QT离散度(QTd),并对其与临床关系进行分析。结果 (1)63例中50例出现心电图缺血样改变,异常率为79.36%。ECG中有心电图缺血样改变者死亡12例(24.00%),无此改变者死亡1例(7.69%)。两组比较预后有统计学意义(P<0.05)。(2)昏迷的基底动脉尖综合症患者心电图缺血样改变数明显多于非昏迷的患者,且QT离散度明显延长。结论基底动脉尖综合症患者早期存在心脏电生理异常,并可以反映基底动脉尖综合症患者的病情。与预后密切相关,可作为基底动脉尖综合症判定预后的主要指标之一。

Objective To explore the influence of the onset of ischemic heart disease and QTd to the prognosis for the patients with top of the basilar syndrome. Methods ECGs were done in 63 patients with acute top of the basilar syndrome in the 1st day after hospitalization and QTd was calculated. Then to analyze the relationship between their ischemic heart diseases and clinical outcomes. Results （1）50 out of 63 patients have ischemic heartiseases detected by ECG （79.36%）. 12 deed patients had bad ischemic heart diseases （24.00%）. but only 1 dead patients had no ischemic heart disease. There was a significant prognostic difference between these two groups（P0.05）. （2） The patients in coma state had more ischemic alteration and longer QTd in ECG than that in non-coma patients. Conclusion Patients with top of the basilar syndrome have obvious cardiac electrophysiological abnormality, which closely ralated to prognosis and can be one of the major prognostic markers of top of the basilar syndrome.
