业已证明睡眠时血压下降,但下降程度报导不一。作者对18名病人(6例血压正常,4例未治的高血压,8例已治的高血压)直接测定动脉压,心率和心电图,并连续24小时记录;病人均睡在家里,作息如常。结果:18例在睡眠时收缩压和舒张压均显著下降,不论日间血压值高低或者是否应用降压治疗,睡眠时血压均下降约20％。血压在入睡2小时(仅1例在5小时)下降最大。本文报道的睡眠血压下降程
Blood pressure has been shown to decline during sleep, but the extent of the decline has been reported. The authors measured arterial pressure, heart rate, and electrocardiogram directly in 18 patients (6 normotensive, 4 nontreated and 8 normotensive) and recorded for 24 hours in a row. The patients slept at home and remained as usual . Results: The systolic and diastolic blood pressure of 18 cases decreased significantly during sleep. The blood pressure decreased by about 20% during sleep, no matter the daytime blood pressure or the antihypertensive treatment.
