为了验证夜间一级食管收缩的频率随着睡眠的逐渐加深而下降,二级收缩的频率则总是保持恒定状态这一假说,作者在晚间(23:00～7:00)对年龄在20～38岁的8例健康者(3女,5男)连续测定食管腔内pH(置于LES上5cm)与压力(LES上5及15cm)值,并同时记录脑电图、眼电图及咽肌电图。结果为一级收缩频率自觉醒期的1.42/min(平均值)降至约0.22/min,第二至第四睡眠相降至0.05/min,眼球快速运动期则减少至0.03/min。二级收缩也在
In order to verify that the frequency of esophageal contraction at nighttime decreases with the deepening of sleep, the hypothesis that the frequency of secondary contraction always remains constant, the authors at night (23:00 ~ 7:00) on the age of 20 ~ The 38-year-old 8 healthy people (3 women and 5 men) continuously measured the esophageal intracavitary pH (5 cm in LES) and pressure (5 and 15 cm in LES), and recorded EEG, Pharyngeal EMG. The results showed that the first-order contractive frequency decreased from 1.42 / min (average value) to about 0.22 / min, decreased to 0.05 / min in the second to fourth sleep phases, and decreased to 0.03 / min in the rapid eye movement. Secondary contraction is also
