Circadian variations in blood pressure in junior medical staff were compared during routine working days and days receiving medical emergencies. The overnight work commitment of junior medical staff when receiving medical emergencies causes a loss in the normal circadian blood pressure rhythm, with overnight blood pressure falling 10/11 mmHg less than on routine working days. This supports the hypothesis that circadian blood-pressure changes are activity related rather than dependent upon hormonal variation. Long-term health effects of abolishing such normal circadian rhythms are not known.
研究人员比较了初级医务人员在日常工作日和应对医疗紧急情况日的血压昼夜变化情况。初级医务人员在应对医疗紧急情况时夜间的工作任务,导致正常的血压昼夜节律丧失,夜间血压比日常工作日下降幅度少10/11毫米汞柱。这支持了昼夜血压变化与活动相关而非取决于激素变化的假设。废除这种正常昼夜节律对长期健康的影响尚不清楚。
