BACKGROUND AND OBJECTIVES Thirty-five percent of children experience syncope at least once. Although the etiology of pediatric syncope is usually benign, many children undergo low-yield diagnostic testing. We conducted a quality improvement intervention to reduce the rates of low-yield diagnostic testing for children presenting to an emergency department (ED) with syncope or presyncope. METHO...

Chronic cough, defined as cough lasting for 8 weeks, is one of the most common symptoms of medical importance, and the prevalence in the community is 9–33%.1 A subgroup of patients suffer from the debilitating and distressing disorder of cough syncope, which is difficult to effectively manage and treat. The approach in clinic is to determine an underlying etiology for cough syncope and to treat...

diopathic ventricular fibrillation (VF) is a disease of nknown etiology but with well described clinical (1) and lectrophysiologic (2,3) characteristics. Briefly, young dults present with syncope or cardiac arrest due to olymorphic ventricular tachyarrhythmias in the absence f structural heart disease or identifiable channelopathies 4).

BACKGROUND Some patients with PAH have a history of syncope at presentation. The prognostic implications of syncope in PAH have not yet been well characterized. METHODS This was a single-center cohort study of 378 patients with PAH seen at a dedicated pulmonary ...

Few cases of a left atrial thrombus without mitral valve disease have been reported. We present an unusual case in which a patient presented to the emergency department with syncope and acute cerebral ischemia caused by a ball thrombus originating from the left atrium (LA). An emergency bedside echocardiogram showed the LA ball thrombus intermittently obstructing the mitral orifice and, at time...

Dengue virus infection affects the heart structurally and functionally. Clinical manifestations of cardiac complications secondary to dengue virus infection vary from self-limiting arrhythmias to severe myocardial infarction, leading to hypotension, pulmonary edema, and cardiogenic shock. However, we report a case of dengue hemorrhagic fever (DHF) complicated by a complete heart block. A female...
