OBJECTIVES The purpose of our investigation was to examine serial changes in autonomic nervous system activity along with measurements of hemodynamics and cardiac contractility, in assessing the mechanism(s) that underlie neurally mediated cardiac syncope (NMCS) in children. BACKGROUND Previous research that used heart rate variability analysis alone to understand changes in autonomic activit...

OBJECTIVES We sought to determine whether there are age-related differences in vasovagal syncope. BACKGROUND In those with suspected vasovagal (neurocardiogenic) syncope, tilt testing demonstrates different hemodynamic responses. These responses may be age related, reflecting differing underlying pathophysiology. METHODS Using a two-stage tilt protocol with glyceryl trinitrate (GTN) provoca...

Sleep apnea is a common disorder associated with obesity and related health problems. Although treatment of sleep apnea may relieve some autonomic symptoms, it is currently unknown whether treatment of sleep apnea is specifically associated with the resolution of orthostatism and syncope. Herein we describe a 73-year-old man who had recurrent episodes of syncope. An extensive work-up, including...

STUDY DESIGN Multi-centre, prospective observational study. OBJECTIVES Main objective is to verify the value of implantable loop recorder (ILR) in assessing the mechanism of syncope and the efficacy of the ILR-guided therapy after syncope recurrence. INCLUSION CRITERIA Patients who met the following criteria are included: suspected or definite neurally mediated syncope based on initial eval...

Objective: Through this surgical series, we present the epidemiological and anatomical-clinical aspects results concerning patients operated on for a primary cardiac tumor at Abidjan Heart Institute. Materials Method: This is retrospective descriptive study covering period of January 1982 to December 2022, based medical records Results: Twenty-seven (27) underwent surgery tumor, including 14 wo...

ABSTRACT Objectives Emergency department (ED) patients with unexplained syncope are at risk of experiencing an adverse event within 30 days. Our objective was to systematically review the accuracy multivariate stratification scores for identifying adult high and low over next Methods We conducted a systematic electronic databases (MEDLINE, Cochrane, Embase, CINAHL) from database creation until ...

BACKGROUND Syncope is a common clinical problem that often remains undiagnosed despite extensive and expensive diagnostic evaluation. OBJECTIVES To assess the diagnostic evaluation, costs and prognosis of patients hospitalized for syncope in a tertiary referral center according to discharge diagnosis. METHODS We retrospectively reviewed the medical records of patients with a diagnosis of sy...

RATIONALE The initial presenting symptoms and signs of acute aortic dissection are so diverse that it makes early and accurate diagnosis arduous. Painless and convulsive syncope due to cardiac arrhythmia were not typical presentations of acute aortic dissection. PATIENT CONCERNS A 61-year-old male presenting with transient consciousness loss and suspected seizure attack was sent to emergency ...

Syncope caused by cardiac asystole during dobutamine stress echocardiography occurred in a 60 year old woman presenting with chest pain and a non-diagnostic exercise test. Cardiac asystole was not associated with myocardial ischemia and was attributed to a powerful cardioinhibitory vagal reflex elicited by the stimulation by the drug of cardiac and aortic mechanoreceptors. Cardiac asystole was ...

and Introduction Introduction Syncope or near-syncope spells are a relatively common occurrence in older children and adolescents. It has been estimated that 15–30% of adolescents will have at least one episode of syncope before reaching adulthood, with approximately half having multiple episodes. Orthostatic intolerance, recurrent syncope or near-syncope when rising from a seated or lying posi...
