本文通过对原因不明的顽固性咳嗽的病因学诊断进行归纳总结，阐述顽固性咳嗽的7个重要的病因诊断，包括鼻后滴漏综合征、咳嗽变异型哮喘、胃食管返流、肝癌、血管紧张素转换酶抑制剂（ACEI）药源性、室性早搏（心源性）和癔症，明确病因诊断可以使大多数患者得到病因学治疗而痊愈。临床诊疗工作中需注意鉴别诊断，不断提高临床诊断的准确性。

Etiological Diagnosis of Cryptogenic Intractable Cough

This paper sums up the etiological diagnosis of cryptogenic intractable cough and illustrates seven critical etiological diagnoses of intractable cough, including postnasal drip syndrome, cough variant asthma, gastroesophageal reflux, liver cancer, angiotensin-eonverting enzyme inhibitors （ACEI） drug-induced, ventric-ular premature beats （cardiogenie） and hysteria. Definite etiological diagnosis can get most patients treated with etiological treatment and recovered. Differential diagnosis shall be emphasized in clinical diagnosis and treatment to improve accuracy in clinical diagnosis.
