In 12 patients with nocturnal angina pectoris, all-night continuous polygraphic recordings were made, including electroencephalogram, electrooculogram, electromyogram, impedance pneumogram and electrocardiogram, and ECG was analyzed in relation to heart rate and sleep stages. Out of 58 episodes of ischemic ST,T changes which were recorded with the peak frequency between 4:00 and 6:00a.m., 24 we...
BACKGROUND The purpose of this study was to examine the effect of sleep deprivation on flow experience. METHODS Sixteen healthy male volunteers of mean age 21.4±1.59 (21-24) years participated in two experimental conditions, ie, sleep-deprivation and normal sleep. In the sleep-deprived condition, participants stayed awake at home for 36 hours (from 8 am until 10 pm the next day) beginning on ...
A 49 yr old poliomyelitic patient had been under cuirass-type nocturnal negative pressure ventilation for more than 20 yrs. He had a severe restrictive ventilatory impairment, and normal awake blood gases at rest and during light exercise. He was offered a trial of intermittent positive pressure ventilation applied through the nose (nIPPV). Two daytime studies and one night study were carried o...
Genetically altered mice may provide useful models for exploring cardiovascular regulation during pregnancy and postpartum if changes in mice mimic humans. We found in awake ICR (CD-1) mice at 17.5 days gestation that hematocrit was reduced 18%, and the pressor response to intravenous angiotensin II was reduced ~33%. Arterial pressure in awake mice was 12% lower in early pregnancy (3.5 days) th...

Saccades, including fast phases of nystagmus, disappear during drowsiness and non-rapid eye movement (NREM) sleep, but are present during the alert state and REM sleep. The purpose of this study was to determine whether spontaneous nystagmus is present in patients with vestibular neuritis during REM sleep. Eight patients with spontaneous nystagmus due to vestibular neuritis and eight control pa...
The sleep pattern and oxygenation of 10 patients undergoing laparoscopic cholecystectomy were studied on the night before operation and the first night after operation. Operations were performed during general anaesthesia and postoperative analgesia was achieved without the administration of opioids. There were no significant changes in the total time awake or the number of arousals on the post...
Objectives: To compare night-time muscle activity in children with cerebral palsy (CP) that typical developing peers. Methods: Polysomnography electroencephalography (EEG), electrocardiogram, electromyography (EMG), respiration, and electrooculography movements recorded during one night were used to characterize sleep stages a group of CP (Gross Motor Function Classification Scale I–III) typica...
