Background Syncope is frequently seen in the Emergency Department (ED) and is a cause for numerous hospitalizations. Focusing primarily on syncope, the aim of this study was to determine the frequency and the underlying causes of transient loss of consciousness in patients seen in the ED. Furthermore, the aim was to identify the indications for admittance and discharge of patients with syncope ...

Swallow syncope (also known as deglutition syncope) is a relatively rare type of syncope that is treatable if diagnosed correctly. We report a case of a 39-year-old man with recurrent swallow syncope. The patient did not have structural heart disease. He developed a complete atrioventricular block upon drinking a cold beverage (Chilsung cider) while undergoing a repeated head-up tilt test. The ...

Pulmonary Embolism andDeepVenous Thrombosis in Patients HospitalizedWith Syncope: AMulticenter Cross-sectional Study in Toronto, Ontario, Canada The prevalence of pulmonary embolism (PE) among patients hospitalized with syncope is uncertain. The recently published Pulmonary Embolism in Syncope Italian Trial (PESIT)1 systematically evaluatedpatientshospitalizedwith a first episode of syncope and...

Symptoms of orthostatic intolerance including syncope, dizziness and unexplained falls affect millions people worldwide, and may result in long-term disability. Syncope affects 35-45% of population [1-3], accounts for 1-3% of emergency visits and up to 6% of all hospitalizations [4]. The majority of syncope cases remain unexplained (37-50%) [5,6] although the known causes of syncope include ref...

We report a rare case of large left atrial myxoma that manifested as syncope in patient who presented to the hospital following syncopal episode. Our had history hypertension and anemia with reported two months dyspnea on exertion. He was found have myxoma. Atrial myxomas are most common benign primary cardiac tumors. Patients may be asymptomatic or experience shortness breath, palpitations, sy...

Neurally mediated syncope is a disorder of the autonomic regulation of postural tone, which results in hypotension, bradycardia, and loss of consciousness. A wide variety of stimuli can trigger this reflex, the most common stimulus being orthostatic stress. Typically, a patient with neurally mediated syncope experiences nausea, lightheadedness, a feeling of warmth, and pallor before abruptly lo...

INTRODUCTION AND OBJECTIVES Little information is available on the evolution of pediatric patients with vasovagal syncope. We therefore aimed to assess the medium-term clinical outcome of children evaluated by tilt testing for syncope of unknown origin. PATIENTS AND METHOD Fifty-one children under 17 years of age who had undergone tilt testing were identified from a data base and studied pros...

The article by Kouakam et al. in issue 22/17 is a prospective observational study of syncope recurrence in 101 children (mean age 12·6 3; range 7–18 years) undergoing head-up tilt testing for investigation of recurrent unexplained syncope or presyncope. Data are presented for patients recruited between 1990 and 1998, and followed-up for an average of 4 years. Head-up tilt was initially positive...

AIMS The hypotensive reflex responsible for vasovagal syncope appears related to a reduction in sympathetic neural outflow. Several animal studies suggest that serotonin may play a role in the genesis of this reflex, through inhibition of sympathetic activity. However, the role of the serotonergic system is unknown in humans. The purpose of the study was to investigate the role of the serotoner...
