Biomarkers and Hemodynamic Parameters in the Diagnosis and Treatment of Children with Postural Tachycardia Syndrome and Vasovagal Syncope

International Journal of Environmental Research and Public Health, 2022
In children, vasovagal syncope and postural tachycardia syndrome constitute the major types of orthostatic intolerance. The clinical characteristics of postural tachycardia syndrome and vasovagal syncope are similar but their treatments differ. Therefore,

Needle phobia and malignant vasovagal syndrome [PDF]

Anaesthesia, 1998
A case is reported in which suspicion of malignant vasovagal syndrome was aroused by a history of faints and needle phobia. The vasovagal response was successfully avoided using a gaseous induction of anaesthesia with sevoflurane. Intravenous access was achieved under general anaesthesia.

Heart Rate Variability in Patients with Vasovagal Syndrome

PACE - Pacing and Clinical Electrophysiology, 1992
The aim of this study was to assess the heart rate variability in patients with vasovagal syndrome (WS). Heart rate variability was expressed as: (1) the standard deviation (SD) of the mean RR interval; and (2) the SD as a percentage of the mean RR interval (%SD). Heart rate variability was measured in VVS patients and compared with control individuals.

Entropy in description of vasovagal syndrome

2015 Computing in Cardiology Conference (CinC), 2015
In this paper we present an example of application of Approximate Entropy and Sample Entropy in analysis of vasovagal syndrome. In our research we conducted an analysis based on three types of data: RRI (RR intervals), SBP (systolic blood pressure) and TPR (total peripheral resistance), which were measured simultaneously with the head up tilt table ...

The Management of Vasovagal Syncope in a Patient with Brugada Syndrome

Cardiac Electrophysiology Clinics, 2012
Vasovagal syncope is the most common cause of the neurally mediated reflex syncopes. A higher susceptibility to vasovagal syncope has been reported in patients with Brugada syndrome (BrS) and may be caused by associated autonomic dysfunction. It is unclear what risk vasovagal syncope confers to patients with BrS.

The incidence of malignant vasovagal syndrome in patients with recurrent syncope.

European Heart Journal, 1991
We reviewed 322 patients with recurrent syncope between 1984 and 1988. Investigation included limited intracardiac electrophysiological study in all cases with programmed extra-stimulus studies in 48 cases. In 93 patients (29%), all investigations were normal, (including negative extrastimulus in 30).
