Children with transient loss of consciousness: Clinical characteristics and the effectiveness of diagnostic tests

open access: yesPediatrics and Neonatology, 2020
Background: Transient loss of consciousness (TLOC) is common among children and adolescents. The aims of this study were to identify clinical differences between patients with vasovagal syncope and those with epileptic seizures, which account for a large

Wavelet Analysis of Blood Pressure Waves in Vasovagal Syncope [PDF]

open access: yes, 1999
We describe the multiresolution wavelet analysis of blood pressure waves in vasovagal syncope affected patients compared with healthy people one. We argue that there exist subtle discriminating criteria which allow us to isolate particular features ...

Clinical Significance and Management of Atrioventricular Block Associated With Bradycardic/Antiarrhythmic Drug Therapy: Drug‐Induced or Drug‐Revealed?

open access: yesJournal of Cardiovascular Electrophysiology, Volume 36, Issue 7, Page 1643-1653, July 2025.
Schematic representation of the management pathway in drug‐related advanced atrioventricular block. ABSTRACT The development of advanced atrioventricular block (AVB) in patients on bradycardic and/or antiarrhythmic therapy (drug‐related AVB) represents a clinical challenge, raising the question of whether the AVB is directly caused by these agents ...

Non-pharmacological methods of treatment and prevention of vasovagal syncope

open access: yesJournal of Education, Health and Sport, 2018
Fainting is a transient loss of consciousness resulting from a momentary ischemia of the central nervous system. One type of syncope is vasovagal syncope, otherwise known as reflex or neurogenic syncope. The consequence of fainting may be a fallen injury.

EFFECT OF SHOCK REPOSITION ON OXYGEN SATURATION IMPROVEMENT IN VASOVAGAL SYNCOPE CASE [PDF]

open access: yes, 2016
BACKGROUND: Vasovagal syncope (a.k.a. neurocardiogenic syncope) occurs when a person faints because his/her body overreacts to a certain trigger, such as the sight of blood or extreme emotional distress.

Contemporary use and safety of prepartum autologous blood donation: A retrospective cohort study in Quebec, Canada

open access: yesTransfusion, Volume 65, Issue 7, Page 1264-1272, July 2025.
Abstract Background Autologous blood donation (ABD) can be indicated in pregnant individuals with rare blood groups. Yet, unlike hospitals, some blood establishments are reluctant to collect ABDs in this population. Therefore, we evaluated the safety and use of prepartum ABD conducted by a blood establishment.

Multistructure index characterization of heart rate and systolic blood pressure reveals precursory signs of syncope

open access: yesScientific Reports, 2017
Recurrent syncope — abrupt loss of consciousness — can have a serious impact on patients’ quality of life, comparable with chronic illnesses. Vasovagal syncope (VVS) is a specific reflex syncope, in which an inappropriate reaction of the autonomic ...
