Different stages of sleep are associated with significant variability in cardiovascular function, which is mediated by marked changes in balance between 2 components of the autonomic system: parasympathetic and sympathetic. Autonomic control of circulation is essential in ensuring an adequate blood flow to vital organs through constant adjustments of arterial blood pressure, heart rate, and redistribution of blood flow. Fluctuations in components of the autonomic nervous system synchronize with electroencephalographic activity during arousal or different stages of sleep. As a result, these can lead to several cardiovascular consequences in those who have underlying heart disease or sleep-disordered breathing.
睡眠的不同阶段与心血管功能的显著变化相关，这是由自主神经系统两个组成部分（副交感神经和交感神经）之间平衡的显著变化介导的。自主神经系统对循环的控制对于通过不断调整动脉血压、心率和血流再分配来确保重要器官有足够的血流至关重要。在觉醒或睡眠的不同阶段，自主神经系统各组成部分的波动与脑电图活动同步。因此，这可能会给患有潜在心脏病或睡眠呼吸紊乱的人带来多种心血管方面的后果。
