Efficacy of high sodium intake in a boy with instantaneous orthostatic hypotensionClinical Autonomic Research - Tập 12 - Trang 47-50 - 2002
Mototada Shichiri, Hidetaka Tanaka, Ryuzo Takaya, Hiroshi Tamai
We report the case of a 14-year-old boy with instantaneous orthostatic hypotension (INOH) with symptoms of orthostatic intolerance. We investigated the effect of high sodium intake on hemodynamics and circulatory responses to orthostatic stress using Portapres. Moreover, a multifrequency bioelectrical impedance method was used to confirm increased plasma volume. Although we began treatment with a...... hiện toàn bộ

Autonomic symptoms, cardiovascular and sudomotor evaluation in de novo type 1 narcolepsyClinical Autonomic Research - Tập 30 - Trang 557-562 - 2020
Camilla Rocchi, Fabio Placidi, Chiara Del Bianco, Claudio Liguori, Antonio Pisani, Nicola B Mercuri, Francesca Izzi
To evaluate cardiovascular and sudomotor function during wakefulness and to assess autonomic symptoms in de novo patients with type 1 narcolepsy compared to healthy controls. De novo patients with type 1 narcolepsy (NT1) and healthy controls underwent cardiovascular function tests including head-up tilt test, Valsalva maneuver, deep breathing, hand grip, and cold face, and sudomotor function was a...... hiện toàn bộ
Forearm vascular responses during orthostatic stress in control subjects and patients with posturally related syncopeClinical Autonomic Research - Tập 10 - Trang 57-61 - 2000
C. M. Brown, R. Hainsworth
The aim of this study was to compare the changes in forearm vascular resistance that occurred during orthostatic stress in asymptomatic volunteer subjects with those in patients with posturally related syncope. The authors hoped firstly that it would indicate the importance of vasoconstriction in the maintenance of blood pressure, and secondly that it might have diagnostic value if there were diff...... hiện toàn bộ
Relative burst amplitude in human muscle sympathetic nerve activity: a sensitive indicator of altered sympathetic trafficClinical Autonomic Research - Tập 8 - Trang 95-100 - 1998
Yrsa Bergmann Sverrisdóttir, Bengt Rundqvist, Mikael Elam
Microneurographically recorded sympathetic outflow to the human muscle vascular bed is traditionally quantified by identifying pulse-synchronous bursts of impulses in a mean voltage neurogram and expressing them in terms of bursts per minute (burst frequency) or bursts per 100 heart beats (burst incidence). As both these measures show large inter-individual differences in resting healthy subjects,...... hiện toàn bộ
