Laboratory studies and a single field study have shown that heart rate in some reptiles is faster during heating than during cooling at any given body temperature. This phenomenon, which has been shown to reflect changes in peripheral blood flow, is shown here to occur in the lizard Varanus va...
At the same time, scopolamine also produced a significant dry mouth. These findings suggest that the effects of scopolamine in low doses on the above cardiac variables are vagomimetic. 展开 关键词: Muscarinic cholinergic central posture heart rate R-R variance ...
Heart rate variability, a target for the effects of angiotensin II in the brain of the trout Oncorhynchus mykiss. This study was conducted on unanesthetized rainbow trout equipped with two ECG electrodes and with an intracerebroventricular (i.c.v.) micro-guide. The ECG... JCL Mével,N Mimas...
This study presents initial documentation of the changes in heart rate of wood frogs (Rana sylvatica) during nonlethal freezing. Heart rate was determined by measuring the electrocardiogram of frogs. Within 1 min of the onset of freezing the heart rate nearly doubled to approximately 8.0 beats/...
Change in cerebral hemodynamics is a net effect resulting from a combination of multiple pathophysiological factors that challenge CA in OSAS, e.g., cerebral deoxygenation, cardiac output and heart rate (HR), intrathoracic pressure (ITP) swings, hypercapnia, hypoxia, sleep stages and arousals. For...
To investigate this phenomenon in detail we studied the dynamics of motor cortex beta oscillations in EEG and the changes in heart rate (HR) during visual cue-paced foot MI using a go (execution of imagery) vs. nogo (withholding of imagery) paradigm in 16 healthy subjects. Both execution ...
changes in measures of heart rate variability and repolarization. We used data from panel studies in Augsburg, Germany, and Rochester, New York, USA, and two controlled human exposure studies in Rochester. Data included ECG recordings from all four studies, controlled exposures to (concentrated) ...
