The dominant feature of neurally mediated syncope (NMS) is loss of consciousness resulting from hypotension, alone or with bradycardia. The causes of NMS have been debated for sixty years and are still not fully understood; it is accepted that there may not be an identifiable physical or psychologic stressor that triggers NMS. Increased availability of certain procedures, such as head-up tilt study and long-term ambulatory event monitoring, provides an opportunity to diagnose NMS more accurately. A case study shows that effective treatment and control of syncope gives patients confidence and independence.
神经介导性晕厥（NMS）的主要特征是因低血压单独或伴有心动过缓导致意识丧失。NMS的病因已争论了60年，至今仍未完全明确；人们认为，可能不存在可识别的身体或心理应激源触发NMS。某些检查手段的增多，如直立倾斜试验和长期动态事件监测，为更准确地诊断NMS提供了机会。一项病例研究表明，有效治疗和控制晕厥可给予患者信心和独立性。
