Mechanisms of orthostatic intolerance during heat stress.
 

Author(s): Zachary J Schlader, Thad E Wilson, Craig G Crandall

Journal: Auton Neurosci. 2016 Apr;196():37-46.

 

Heat stress profoundly and unanimously reduces orthostatic tolerance. This review aims to provide an overview of the numerous and multifactorial mechanisms by which this occurs in humans. Potential causal factors include changes in arterial and venous vascular resistance and blood ...

Author(s): Emily M Garland, Jorge E Celedonio, Satish R Raj

Journal: Curr Neurol Neurosci Rep. 2015 Sep;15(9):60.

 

Postural tachycardia syndrome (POTS) is a form of chronic orthostatic intolerance for which the hallmark physiological trait is an excessive increase in heart rate with assumption of upright posture. The orthostatic tachycardia occurs in the absence of orthostatic hypotension and ...
