Delaying orthostatic syncope with mental challenge: a pilot study.

At orthostatic vasovagal syncope there appears to be a sudden decline of sympathetic activity. As mental challenge activates the sympathetic system, we hypothesized that doing mental arithmetic in volunteers driven to the end point of their cardiovascular stability may delay the onset of orthostatic syncope. We investigated this in healthy male subjects. Each subject underwent a head up tilt (H...

Distinctive Steady-State Heart Rate and Blood Pressure Responses to Passive Robotic Leg Exercise during Head-Up Tilt: A Pilot Study in Neurological Patients

Introduction: Robot-assisted tilt table therapy was proposed for early rehabilitation and mobilization of patients after diseases such as stroke. A robot-assisted tilt table with integrated passive robotic leg exercise (PE) mechanism has the potential to prevent orthostatic hypotension usually provoked by verticalization. In a previous study with rather young healthy subjects [average age: 25.1...

Rate of cardiovascular recovery to combined or separate orthostatic and mental challenges.

Post stress neurovascular responses induced by physical and mental stress are poorly understood. We investigated the time course of cardiovascular and autonomic recovery, induced by orthostatic and mental challenge, using passive head up tilt (HUT) and mental arithmetic (MA), respectively, when applied singly (MA, HUT) or in combination (MA+HUT). Fifteen healthy males participated in three prot...

Comparison of intrabrachial and finger blood pressure in healthy elderly volunteers.

This study was performed to compare continuous Finapres (FIN) and intrabrachial (IAP) blood pressure in healthy elderly volunteers. Fifteen elderly subjects (age 71 to 83) without cardiovascular disease and an intraarterial mean (range) systolic and diastolic blood pressure of 162 (122 to 195) and 73 (62 to 88) mm Hg, respectively, participated in the study. A 10-min head-up tilt, 10 min active...

Long-term exposure to microgravity impairs vestibulo-cardiovascular reflex

The vestibular system is known to have an important role in controlling blood pressure upon posture transition (vestibulo-cardiovascular reflex, VCR). However, under a different gravitational environment, the sensitivity of the vestibular system may be altered. Thus, the VCR may become less sensitive after spaceflight because of orthostatic intolerance potentially induced by long-term exposure ...
