摘要
目的探讨缺血性中风发病时间的昼夜分布规律。方法采用圆形分布对263例缺血性中风患者的发病时间进行统计分析。结果缺血性中风发病的高峰时点平均为8∶21,标准差(s)为4小时零3分,95%的缺血性中风发病时段为0∶25~16∶17。结论圆形分布对于昼时性资料是否具有集中趋势提供良好的统计分析,缺血性中风的发病时间存在昼夜24h的分布差异。
Objective To study ischemic stroke events and its
circadian variadions.Methods By using circular distribution,to find out diural variations in 263
acute ischemic stroke cases.Results Acute ischemic stroke occurred on an average in the
morning 8∶21(am).The standrad error was four hours.95% onset time was from 0∶25 (am)to 4∶
17(pm).Conclusions The ischemic stroke onset time has difference distributions in the day and
night.
