Autoimmune Antibodies in Orthostatic Intolerance Syndromes Open
Orthostatic intolerance (OI) is defined as the development of characteristic symptoms while standing, which significantly improve by recumbency. The most common forms are vasovagal syncope (VVS), orthostatic hypotension, and postural ortho…

Postural Orthostatic Tachycardia Syndrome (POTS) of Autoimmune Origin - Case and Review Open
Introduction: Postural Orthostatic Tachycardia Syndrome (POTS) belongs to a group of orthostatic intolerance syndromes. It is defined by the increase in heart rate ≥30 bpm or heart rate higher than 120/min during first 10 minutes after sta…

Application of Liquid Chromatography Coupled to Mass Spectrometry for Direct Estimation of the Total Levels of Adenosine and Its Catabolites in Human Blood Open
Adenosine is a multifunctional nucleoside with several roles across various levels in organisms. Beyond its intracellular involvement in cellular metabolism, extracellular adenosine potently influences both physiological and pathological p…

Theophylline in the prevention of vasovagal syncope recurrences Open
The addition of oral theophylline preparation to non-pharmacological treatment led to a marked reduction of syncopal recurrence in patients with vasovagal syncope. About one-third of study subjects discontinued therapy because of side effe…

Association of Polymorphisms in Endothelin-1 and Endothelin Receptor A Genes With Vasovagal Syncope Open
The endothelin system may play a role in the pathogenesis of vasovagal syncope (VVS) because it is implicated in blood pressure regulation. We hypothesized that endothelin-related genetic polymorphisms might modulate susceptibility to VVS.…

Hemodynamic differences in isometric counter-pressure maneuvers and their efficacy in vasovagal syncope Open
Background Isometric counter-pressure maneuvers (ICM) were proposed as first-line treatment in patients with vasovagal syncope (VVS). The aim was to study hemodynamic mechanisms and effectiveness of ICM in prevention of head-up tilt (HUT)-…

P1791Clinical effect of home tilt training and its impact on the function of the autonomic nervous system in patients with reccurent vasovagal syncope Open
Methods: Cardiac PET was performed in 7 CI patients without structural heart disease and 4 age-matched healthy controls using 11C-CGP12177, a radioligand for beta-adrenergic receptors (age 61.5614.0years;male 54.5%).The maximum number of a…

Beta 3 subunit of G-protein and its influence on autonomic nervous system in patients with vasovagal syncope Open
In this study, the relation of C825T polymorphism of β3 subunit of G-protein to vasovagal syncope was not documented (Tab. 2, Fig. 4, Ref. 37).

Syncope Unit: rationale and requirement – the European Heart Rhythm Association position statement endorsed by the Heart Rhythm Society Open
The European Society of Cardiology (ESC) has played an important role in advancing our understanding of the causes, optimal investigation, and management of syncope through publication of practice guidelines in 2001, 2004, and 2009.1–3 The…
