本组分析了112例SAH的心电图资料,其中82例(73.2%)在第一次检查时有不正常心电图表现。心电图正常组和异常组病人在年龄、性别、入院时血压、血钾浓度、血酯测定、脑血管造影各项中,均无明显相差。但在预后方面二组有明显相差(P<0.05);特别在心电图复查时如无改善或恶化者、预后不佳。和复查时心电图有改善者相比,二者有极显著的差异(P<0.001)。文内对心电图表现的特征和其发生机理进行了讨论。
The group analyzed 112 cases of SAH ECG data, of which 82 cases (73.2%) at the first examination had abnormal ECG performance. Normal ECG and abnormal group of patients in age, gender, admission blood pressure, serum potassium concentration, blood ester determination, cerebral angiography in all the items, no significant difference. However, the prognosis in the two groups were significantly different (P <0.05); especially in the ECG without any improvement or worsening, the prognosis is poor. There was a significant difference (P <0.001) between the two when compared with those with ECG improvement at the time of review. The article discusses the characteristics of ECG presentation and its mechanism.
