为探讨脑血管病患者死亡时间是否存在２４小时节律变化，我们对我院１９９０年１月至１９９２年５月因脑血管病死亡１０４例病人进行了分析。本组资料显示脑血管病患者死亡时间存在２４小时节律变化，在上午６：００～８：００时及下午１８：００～２０：００时出现两个高峰值，夜间死亡率低，并出现统计学差异。这种节律变化与以往报导心脏病猝死时间２４小时节律改变相似。脑血管病患者多死于并发症，如心衰、脑疝等，其死亡时间存在２４小时节律改变可能由这些因素所决定。本组病例在医院内死亡，都经过一些治疗，这些治疗在一定程度上会影响病人的生物节律。
To investigate whether there is a 24-hour rhythm change in the death of patients with cerebrovascular disease, we analyzed 104 patients who died of cerebrovascular disease from January 1990 to May 1992 in our hospital. This group of data show that there is a 24-hour rhythm change in the death of patients with cerebrovascular disease in the morning 6:00 to 8:00 and 18:00 to 20:00 when there are two peaks, low night-time mortality and statistics Differences This rhythm change is similar to the rhythm changes reported 24 hours before the sudden death from heart attack. Patients with cerebrovascular disease often die of complications, such as heart failure, hernia, etc. The 24-hour rhythm change of death time may be determined by these factors. This group of patients died in the hospital, after some treatment, these treatments will to a certain extent affect the patient’s biological rhythm.
