特发性直立性低血压(Idiopathicorthostatic hypotension简称IOH)或称原发性姿势性低血压。是指病因尚不明确的一种神经系统多发性、系统性、变性疾病。是一种少见病。既往认识不清,以致误诊。目前我区尚未见报导。83年我院收治三例,现将三例摘要见列表: IOH的临床表现主要有三方面:(1)直立性低血压及由此而引起的一系列症状。卧位与立位血压波动范围较大,收缩压均大于50mmHg,(有的学者认为由卧位变立位时收缩压下降30mmHg,舒张压下降20mmHg)。但心率无明显变
Idiopathic orthostatic hypotension (IOH) or primary postural hypotension. Refers to the etiology is not yet clear a nervous system multiple, systemic, degenerative diseases. Is a rare disease. Past knowledge is not clear, resulting in misdiagnosis. At present, my district has not yet been reported. 83 cases admitted to our hospital in three cases, now a summary of three cases list: IOH clinical manifestations are mainly three aspects: (1) orthostatic hypotension and the resulting series of symptoms. Supine and upright blood pressure fluctuations range, systolic blood pressure greater than 50mmHg, (some scholars believe that the supine position from the systolic blood pressure decreased 30mmHg, diastolic blood pressure decreased 20mmHg). But no significant change in heart rate
