回顾性分析我院10年间急诊收治的脑梗死患者882例的心电图变化。有心电图变化的700例中ST－T段改变占44．6％，心律失常占38．4％，两者发生率比较有显著性差异（P＜0．001）。40岁以上脑梗死患者合并心电图异常者占97．8％，不同年龄组问异常心电图发生率有显著性差异（P＜0．001）.基底节脑梗死以ST－T段改变多见，占此部位异常心电图的48．1％，下丘脑、颞叶、顶叶、枕叶部位梗死以心律失常多见，占此部位异常心电图的46．8％。缺血性心脑疾病发病基础相似，常伴随发生。 A retrospective analysis of our hospital 10 years emergency treatment of patients with cerebral infarction 882 cases of ECG changes. There were 44.6% changes in ST-T segment and 38.4% arrhythmia in 700 patients with ECG changes, the incidence of ST-T changes was significantly different (P <0.001). Patients with cerebral infarction over 40 years of age with ECG abnormalities accounted for 97.8%, different age group asked abnormal ECG incidence was significantly different (P <0.001) .Central cerebral infarction ST-T segment changes more common, accounting for 48.1% of abnormal ECG in this site, arrhythmia is more common in the hypothalamus, temporal lobe, parietal lobe, occipital lobe, accounting for 46.8% of the abnormal ECG in this site. The basis of the pathogenesis of ischemic heart and brain disease is similar, often accompanied.
