Sympathetic dysfunction in vasovagal syncope and the postural orthostatic tachycardia syndrome

Frontiers in Physiology, 2014
Orthostatic intolerance is the inability to tolerate the upright posture and is relieved by recumbence. It most commonly affects young women and has a major impact on quality of life and psychosocial well being.

Orthostatic intolerance after space flight [PDF]

The Journal of Physiology, 2002
Physiologists have always been challenged by the adjustments of the human body to hostile environments. The set of papers in this issue of The Journal of Physiology (Cox et al. 2002; Ertl et al. 2002; Levine et al. 2002) fits into the tradition of the study of human responses to extreme physical circumstances.

Cardiovascular Autonomic Dysfunction Is the Most Common Cause of Syncope in Paced Patients

Frontiers in Cardiovascular Medicine, 2019
Introduction: Syncope and orthostatic intolerance in paced patients constitute a common clinical dilemma. We, thus, aimed to determine the etiology of syncope and/or symptoms of orthostatic intolerance in paced patients.Methods: Among 1,705 patients with

Archives of internal medicine, 1992
In seven patients who presented with lightheadedness, fatigue, "weakness," and sometimes syncope, blood pressure was found not to fall after standing for 3 to 4 minutes but to fall severely, frequently with syncope or presyncopal symptoms, after 13 to 30 minutes when measured every minute with an automatic device.

Severe orthostatic hypotension in otherwise uncomplicated Plasmodium vivax infection

Malaria Journal, 2021
Impaired autonomic control of postural homeostasis resulting in orthostatic hypotension has been described in falciparum malaria. However, severe orthostatic intolerance in Plasmodium vivax has been rarely reported.
