ABSTRACT
Objective:To explore the relationship between abnormal ECG and cerebral vasospasm(CVS)after aneu-rysmal subarachnoid hemorrhage(aSAH).Methods:A total of 709 aSAH cases,who were hospitalized in our de-partment of neurology from Feb 2002 to Feb 2015,were selected.According to presence of CVS or not,they were divided into non-CVS control group(n=499)and CVS group(n=210).All subjects received ECG examination, then single factor and multi-factor Logistic regression were used to analyze the relationship among bradycardia, tachycardia,prolonged QT interval,ST segment elevation,ST segment depression,T wave inversion,u wave pres-ence and CVS after aSAH.Results:Single factor regression analysis indicated that bradycardia,prolonged QT inter-val,ST segment elevation,ST segment depression,T wave inversion and u wave presence were risk factors for CVS after aSAH,P<0.05 or <0.01. Multi-factor Logistic regression analysis indicated that prolonged QT interval was independent risk factor for CVS after aSAH(OR=13.502,P=0.001).Conclusion:For aSAH patients with cere-bral vasospasm high risk factors(abnormal ECG),monitoring should be strengthened in order to reduce or avoid oc-currence of cerebral vasospasm,then improve their prognosis.
