Analysis of temporal rhythm of cerebrovascular accidental death in 144 cases

Objective To investigate the cirannual rhythm,monthly rhythm and circadian rhythm of cerebrovascular accidental death for immediate clinical prevention treatment.Methods The data were collected by epidemiological methods and compared with χ+2 test and round distribution.Results ①The death time of intracerebral hemorrhage tended to occur before midnight with circadian rhythm.②The death time of cerebral infarction tended to occur in winter and after midnight with cirannual rhythm and circadian rhythm.Conclusion There is circadian rhythm in the death time of intracerebral hemorrhage and cirannual rhythm and circadian rhythm in the death time of cerebral infarction.
