Fifteen patients aged 10 to 18 years with syncope of unknown origin, and 10 healthy control children aged 11 to 18 years, were evaluated by head-up tilt to 60 degrees for 60 minutes. Six patients (43%) reproduced symptoms of syncope during the examination. Four had a typical vasovagal reaction; two had marked hyperventilation. None of the children in the control group had syncope. The head-up t...

Study Objective: Syncope is one of the most common presentation of patients seen in emergency departments (ED). Risk assessment of syncope is challenging. The San Francisco Syncope Rule is the most widely used risk assessment, but has moderate accuracy. The aim of our study was to investigate blood biomarkers as prognostic factors for adverse outcome. Methods: In this observational study we inc...

AIMS We correlated the finding of cardioinhibitory carotid sinus hypersensitivity (CSH) with that observed during a spontaneous syncopal relapse by means of an implantable loop recorder (ILR). METHODS AND RESULTS We included 18 consecutive patients with suspected recurrent neurally mediated syncope and positive cardioinhibitory response during carotid sinus massage (max pause 5.5 +/- 1.6 s) w...

INTRODUCTION Anomalies in the craniovertebral junction may be a rare cause of syncope. The mechanisms of syncope related to craniovertebral junction anomaly remain unknown.We present an extremely rare case with anomaly in the craniovertebral junction and syncope, and discuss the mechanism of the syncope. CASE PRESENTATION A 10-year-old Japanese boy with a congenital anomaly in the cranioverte...

Epidural anesthesia was performed for a cesarean section in a patient with vasovagal syncope. A 26-year-old woman at 41 weeks of gestation and with a known history of vasovagal syncope was scheduled to undergo an emergency cesarean section. She received epidural anesthesia for the cesarean delivery and showed signs and symptoms of vasovagal syncope, which were treated successfully with fluids a...

Syncope in childhood is very common. The vast majority of episodes are benign, and are due to neurocardiogenic syncope. Only a minority are due to something potentially more serious or life threatening. The diagnosis and differentiation of benign from more serious causes of syncope is made primarily by the history. Investigations are often unfruitful. The mainstay of management in neurocardioge...

Patients with syncope are usually referred to either neurology or cardiology clinics, yet the facilities for detailed syncope investigation are mostly in cardiac units. The diagnosis rests principally upon the history, but investigations may be required to support the clinical diagnosis. Close collaboration between the epilepsy clinician and a cardiologist is essential for effective investigati...

There are three major types of syncope: neurally mediated (the most common), orthostatic hypotensive, and cardiac (the most worrisome). Several studies have shown a normal long-term survival rate in patients with syncope who have no structural heart disease, which is the most important predictor of death and ventricular arrhythmia. The workup of unexplained syncope depends on the presence or ab...

Cardiac sinus syncope is a recognised but rare complication of head and neck cancers. Although electrical pacing remains an important treatment to prevent further syncopal episodes related to bradycardia, vasopressor-related syncope remains a more difficult management problem. The article describes the case of a 66-year-old patient with metastatic squamous cell carcinoma of the nose, who presen...

This paper presents a practice-oriented approach to the problem of syncope in pediatrics. Autonomic syncope is the major etiologic category in pediatrics and consists of 2 types: reflex and dysautonomic. The latter type is rare in pediatrics. Reflex syncope has 4 subtypes: neurocardiogenic, central, situational, and cerebral. Neurocardiogenic syncope, the most common subtype, is easily diagnose...
