复发性晕厥是临床医生常见的一个棘手的问题.美国的调查资料表明,复发性晕厥占每年住院病人总数的6%,占所有急诊观察病人的3%.尽管使用了心电图、Holter监测、头部CT、糖耐量试验等多种传统诊断方法,仍有4%的病人找不到这种复发性病症的原因.目前认为,大多数不明原因的复发性晕厥是由血管神经诱导的短暂性、无法预测的低血压和心动过缓所致.本文回顾了血管神经性晕厥的病理生理和斜台试验使用常规的现代知识,提示如何将这种技术用于不明原因的复发性晕厥的诊断和治疗.
Recurrent syncope is a common problem for clinicians.US data showed that recurrent syncope accounted for 6% of the total number of inpatients per year, accounting for 3% of all emergency patients.Although the use of ECG, Holter monitoring, head CT, glucose tolerance test and other traditional diagnostic methods, there are still 4% of patients can not find the cause of this recurrent disease.It is currently believed that most unexplained recurrent syncope is induced by the transient vascular nerves, can not Predicted Hypotension and Bradycardia This review reviews the pathophysiology of neuropathic syncope and the ramp test using routine modern knowledge that suggests how to use this technique for the diagnosis and treatment of unexplained recurrent syncope.
