Syncope is defined as the transient loss of consciousness with spontaneous recovery, as a result of cerebral hypoperfusion. It is a very common clinical entity.1 Although it is difficult to establish the prevalence and incidence of syncopal episodes, recent data indicate that 9-35% of the Spanish population present some syncopal episode in their lifetime.2,3 There are a variety of causes which ...

BACKGROUND Pediatric syncope is common. Cardiac causes are rarely found. We describe and assess a pragmatic approach to these patients first seen by a pediatric cardiologist in the New England region, using Standardized Clinical Assessment and Management Plans (SCAMPs). METHODS AND RESULTS Ambulatory patients aged 7 to 21 years initially seen for syncope at participating New England Congenita...

Cough syncope typically occurs in middle aged and senior, muscularly built males with a history of chronic obstructive lung disease. Originally, cough syncope was thought to be a form of epilepsy and only in the 1940s it was recognized to be of syncopal nature. The circulatory pathophysiology is, however, still not fully understood. We present data on two cough syncope patients in whom we docum...

In normal children, any procedure that increases heart rate, such as the tilt test, may shorten the QT interval. The effect of the tilt test on QT interval in children with syncope remains unknown. We analyzed the response of RR and QT intervals during a tilt test in 3 groups of children: 28 healthy children (group 1), 26 with syncope of unknown etiology and negative tilt test results (group 2)...

supravalvar mitral ring is a rare congenital heart defect of surgical importance. the condition is characterized by an abnormal ridge of the connective tissue on the atrial side of the mitral valve. it often substantially obstructs the mitral valve inflow. we herein introduce a case of a supravalvar mitral ring in a 17-year-old male, who was admitted to our hospital with cardiac syncope. he had...

Falls in older adults are often the result of syncope, commonly defined as “a transient loss of consciousness.” Identifying the cause of syncope can be quite difficult, especially since syncoperelated falls in older adults are often not witnessed. A systemic approach can help distinguish between neuroautonomic and cardiac syncope, identify syndromes with syncopelike symptoms, and prevent fallre...
