Arterial blood pressure (AP) increases during the transition from non-REM to REM sleep, showing phasic surges during REM sleep. REM-associated AP changes involve 1) a long-term recovery process after surgery, 2) circadian rhythm, 3) relationships with ambient temperature.

2012年9月1日 · Blood pressure displays large fluctuations during REM sleep, a period when skeletal muscle loses activity systemically. Blood pressure rises spontaneously in spike-like surges even with no body movement. The mechanism underlying this unique characteristic of cardiovascular control during REM sleep remains unclear.

Rapid-eye-movement sleep (REM sleep) physiologically entails arterial pressure surges. Pressure surges may lead to acute cardiovascular events in risk conditions such as arterial hypertension. We investigated whether arterial hypertension alters the rate of occurrence and the characteristics of the pressure surges during REM sleep.

We hypothesized that in OSA patients (in REM and NREM sleep), BP declines (dips) less frequently during REM sleep than NREM sleep. Therefore, this study sought to noninvasively assess BP-dipping during REM and NREM-sleep using a beat-by-beat measurement method (PTT) in patients who had obstructive events in both REM and NREM sleep.

2019年9月3日 · In this review, we discuss the potential pathophysiologic mechanisms underlying elevated BP in restless legs syndrome/periodic limb movements of sleep, sleep-related bruxism, narcolepsy-cataplexy, and rapid eye movement sleep behavior disorder.

The gain of the down sequences (the amount heart rate increases in response to a drop in blood pressure) is elevated during REM sleep compared with both wake and NREM, while the number of times the reflex is invoked is similar between quiet …

2023年3月9日 · Epidemiological studies have reported that hypertension is associated with respiratory events during REM sleep. We examined the relationship between respiratory events during REM and morning and evening hypertensive blood pressure (BP) levels in a …
