title: Characteristics of syncope in Japan and the Pacific rim.
abstract: As is true in the Western world, syncope of cardiac and non-cardiac origin is one of the common clinical presentations in daily medical practice in Japan and Asia. However, the underlying disorders and social backgrounds associated with syncope may differ, from those encountered in Western countries, particularly in Japan. While non-cardiac causes, neurally-mediated reflex faints in particular, are highly prevalent, out-of-hospital deaths by drowning due to syncope occurring during bathing at home are not rare in Japan, particularly in the elderly. Other underlying cardiac or non-cardiac disorders are also noteworthy, particularly Brugada syndrome and coronary vasospasm, which may present as isolated syncope. In addition, the characteristic clinical presentation of micturition and defecation syncope is not uncommon. This review is focused on these specific underlying diseases in the light of the guidelines issued by the Japanese Circulation Society regarding the diagnosis and treatment of syncope.
