OBJECTIVES: A recent study reported a high prevalence of pulmonary embolism (PE) among patients admitted with syncope. We sought to determine whether these findings were validated in our patient population. METHODS: We performed a retrospective, secondary analysis of prospectively gathered data from patients presenting with syncope to an academic emergency department (ED) from July 2010 to December 2015. We analyzed baseline information from the time of the ED visit, recorded outcomes during the hospital stay, and contacted patients by phone at least 30days after the ED visit...

Syncope is a very commonly encountered clinical problem in general practice and in the emergency department. In the evaluation of syncope, it is important to identify the specific cause to determine the treatment, to estimate the precise risk to a patient, and to reduce recurrence. Sometimes, making a diagnosis of syncope is difficult, as different mechanisms may often coexist. Syncope causes a significant impact on quality of life due to associated risk of physical injury. In particular, syncope can be a precursor to sudden cardiac death in patients with underlying cardiac disease...

The maintenance of blood pressure upon the assumption of upright posture depends on rapid cardiovascular adaptations driven primarily by the autonomic nervous system. Failure of these compensatory mechanisms can result in orthostatic hypotension (OH), defined as sustained reduction in systolic blood pressure > 20 mm Hg or diastolic blood pressure > 10 mm Hg within 3 minutes of standing or > 60° head-up tilt. OH is a common finding, particularly in elderly populations, associated with cardiovascular and cerebrovascular morbidity and mortality...

This is a case report of a 45-year-old man who reported complete amnesia during the very first kilometer of a 10-km run. He was wearing a heart rate monitor (HRM). The interrogation of his HRM watch showed 200 bpm tachycardia beginning in the first kilometer and increasing up to 220 bpm during the last kilometer. The patient was asked to wear a Holter-monitor (Holter Research Laboratory; Helena, Montana USA) electrocardiogram (ECG) while practicing a training session. This examination allowed for the diagnosis of an adrenergic paroxysmal atrial fibrillation (AF) with an impressive auriculo-ventricular conduction over 260 bpm...

BACKGROUND: The differential diagnosis of generalized tonic-clonic seizures (GTCS), psychogenic nonepileptic seizures (PNES), and syncope constitutes a major challenge. Misdiagnosis rates up to 20 to 30% are reported in the literature. PURPOSE: To assess the clinical utility of serum lactate levels for differentiation of GTCS, PNES, and syncope based on gender differences. METHODS: Data from 270 patients were evaluated retrospectively. Only patients ≥18 years old with the final diagnosis of GTCS, PNES, or syncope in their chart were recruited...

INTRODUCTION: Deep vein thrombosis (DVT) continues to be a significant source of morbidity for surgical patients. Placement of a retrievable inferior vena cava (IVC) filter is used when patients have contraindications to anticoagulation or recurrent pulmonary embolism despite therapeutic anticoagulation. Although retrievable IVC filters are often used, they carry a unique set of risks. PRESENTATION OF CASE: A 67-year-old man presents to the Emergency Room (ER) following large volume melena and complaining of syncope...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare genetic disorder characterized by fatty degeneration of the right ventricular myocardium with variable involvement of the left ventricle. The condition is associated with exercise-mediated ventricular tachycardia and is one of the recognized causes of sudden cardiac death in the young and in athletes. Here, we report the first confirmed case of ARVC in Oman and present its electrocardiographic, echocardiographic features, and radiological findings on gated, contrast-enhanced cardiac computed tomography...

Admission rates and expenditures for syncope remain high. This unsatisfactory management could be due to several factors, including lack of evidence-based strategy, poor accuracy of clinical decision rules, difficulty in disseminating guidelines, as well as uncertainties concerning management of intermediate-risk patients and role of observation protocols and syncope units. To optimise management, it has been proposed to adopt a pragmatic, symptoms-based definition of syncope and a classification related to the underlying mechanism rather than suspected aetiology...

OBJECTIVE: Vertical running events, during which participants race up the stairwells of skyscrapers, are becoming increasingly popular. Such events have unique and specific operational and clinical considerations for event medical directors, but descriptions of the medical care provided at these events are lacking. We sought to perform a descriptive analysis of the medical care delivered at a single, large vertical running event. METHODS: A retrospective chart review of medical encounters at a large vertical running event from 2011-2017 was performed...

BACKGROUND: Syncope can be caused by serious occult arrhythmias not evident during initial emergency department (ED) evaluation. We sought to develop a risk-tool for predicting 30-day arrhythmia or death after ED disposition. METHODS: We conducted a multicenter prospective cohort study at six tertiary-care EDs and included adults (≥16 years) with syncope. We collected standardized variables from clinical evaluation, and investigations including ECG and troponin at index presentation...

Quetiapine, an atypical antipsychotic, has been extensively used in patients with bipolar disorder. Overdose of quetiapine can result in severe complications, such as coma, seizure, respiratory depression, arrhythmia, and even death. However, the paucity of toxicological evaluation in adolescence causes more potential risks in this population. Herein, we present a case of hypotension and convulsive syncope after exposure to a small dose of quetiapine in a 16-year-old who was diagnosed with bipolar disorder...

This article focuses on the complex interactions between the cardiovascular and neurologic systems. Initially, we focus on neurological complications in children with congenital heart disease both secondary to the underlying cardiac disease and complications of interventions. We later discuss diagnosis and management of common syncope syndromes with emphasis on vasovagal syncope. We also review the diagnosis, classification, and management of children and adolescents with postural orthostatic tachycardia syndrome...

Infective endocarditis is a rare disease associated with high morbidity and mortality. As a result, early diagnosis and prompt antibiotic treatment with or without surgical intervention is crucial in the management of such condition.We report a case of missed infective endocarditis of the aortic valve. The patient underwent mechanical aortic valve replacement, with the native valve being sent for histopathological examination. On re-admission 16 months later, he presented with syncope, shortness of breathing and complete heart block...

AIMS: Non-ischemic cardiomyopathies (CMPs) comprise heart muscle disorders of different causes with high variability in disease phenotypes and clinical progression. The lack of national structures for the efficient recruitment, clinical and molecular classification, and follow-up of patients with non-ischemic CMPs limit the thorough analysis of disease mechanisms and the evaluation of novel diagnostic and therapeutic strategies. This paper describes a national, prospective, multicenter registry for patients with non-ischemic CMPs...

Congenital atresia of the left coronary artery is a very rare condition. We report a case of a 13-year-old boy who was followed-up at our outpatient clinic from 6 months of age because of heart murmur. He had no symptoms for more than 10 years, and his left ventricular contraction was normal. Exercise electrocardiogram was performed at 7 and 10 years of age, and ST depression was not observed. He presented with chest pain and syncope on exertion at the ages of 11 and 12 years, respectively, and ST depression on exercise electrocardiogram was detected for the first time at 13 years of age...
