Machine Learning Model Using Heart Rate Variability for the Prediction of Vasovagal Syncope
IEEE AccessVasovagal syncope is a reversible condition that can cause serious events, such as cerebral hemorrhage. Predicting its occurrence is challenging; thus, this study aimed to develop machine learning models that use heart rate variability to predict the ...

Structural heart disease as the cause of syncope
Brazilian Journal of Medical and Biological Research, 2018 We described the clinical evolution of patients with structural heart disease presenting at the emergency room with syncope. Patients were stratified according to their syncope etiology and available scores for syncope prognostication.

Vasovagal Syncope in the Older Patient
Journal of the American College of Cardiology, 2008 Vasovagal syncope (VVS) has been diagnosed with increasing frequency in older patients since the head-up tilt-table test (HUT) was described over 2 decades ago. The incidence and prevalence of VVS in this age group remains unknown. Older individuals are more likely to display a dysautonomic hemodynamic pattern with a predominantly hypotensive response ...

Vasovagal syncope interrupting sleep? [PDF]
Heart, 2004 Clinical data are reported for 13 patients who were referred with recurrent loss of consciousness at night interrupting their sleep. Most of the patients were women (10 of 13) with a mean age of 45 years (range 21-72 years). The histories were more consistent with vasovagal syncope than with epilepsy.

False Positive Responses to Head-Up Tilt Testing in Elderly Patients with Paroxysmal Atrial Fibrillation [PDF]
, 2008 The autonomic nervous system (ANS) plays a role as a modulator in the pathogenesis of paroxysmal atrial fibrillation (PAF). The clinical pattern of vagally mediated PAF has been observed mainly in young patients.

Regional anaesthesia for awake urgent upper limb surgery in children: a prospective cohort study
Anaesthesia, Volume 80, Issue 9, Page 1065-1073, September 2025.Summary Introduction Peripheral regional anaesthesia is used rarely as the sole anaesthetic technique in children and is often combined with deep sedation or general anaesthesia for analgesic purposes. No literature addresses the minimum age at which regional anaesthesia can be considered to facilitate awake surgery in children.

Self-organization of blood pressure regulation: Clinical evidence
Frontiers in Physiology, 2016 The pathogenesis of vasovagal syncope has remained elusive despite many efforts to identify an underlying dysfunction. Catastrophe theory explains the spontaneous occurrence of sudden events in some mathematically complex systems known as self-organized ...
