对 5 名受试者在睡眠阶段内由 3 秒听觉刺激引起的心率反应进行平均。虽然存在一些个体差异，但诱发的 HR 反应通常是双相的，加速成分的峰值出现在刺激后第 4 次心跳，减速成分的谷值出现在刺激后第 10 次心跳。与其他在快速眼动 (REM) 阶段被抑制的变量不同，在 REM 阶段 HR 响应往往比其他睡眠阶段更大。反应的大小不会明显受到夜间时间的影响，因为心率在睡眠期间是非习惯性的，但会受到呼吸周期阶段的影响，当刺激发生在吸气期间或吸气之前的一段时间时反应最大，当刺激发生在呼气阶段时反应最小。
Heart rate responses evoked by a 3‐sec auditory stimulus were averaged within stages of sleep for five subjects. Although there were some individual differences, the evoked HR response is generally diphasic, with the peak of the acceleratory component occurring on the fourth post‐stimulus beat and the trough of the deceleratory component occurring on the 10th post‐stimulus beat. Unlike other variables, which are depressed during the rapid eye movement (REM) stage, the HR response tends to be larger during the REM stage than during other stages of sleep. The size of the response is not appreciably affected by time of night, since HR is non‐habituating during sleep, but is affected by the respiratory cycle phase, being largest when the stimulus occurs during inspiration or the period immediately prior to inspiration, and smallest when the stimulus occurs during the expiratory phase.
