title: [Misdiagnosis of obstructive sleep apnea hypopnea syndrome].
abstract: OBJECTIVE
  To enhance the understanding of obstructive sleep apnea hypopnea syndrome (OSAHS) and lower its misdiagnosis.
  
  
  METHODS
  6 misdiagnosed cases were analyzed systemically.
  
  
  RESULTS
  OSAHS can be misdiagnosed as primary hypertension, arrhythmia, asthma, acalcerosis and some other diseases. The main causes of misdiagnosis were: the main complaints and the main signs could be one or more of a series of symptoms or signs of OSAHS itself or its complications and the lack of systemic knowledge of OSAHS.
  
  
  CONCLUSIONS
  The understanding of OSAHS could be enhanced by analyzing misdiagnosis cases.
