Objective To explore the clinical features of atypical bronchial asthma with chief complaint of palpitations. Methods Twelve cases with unexplained palpitations diagnosed by asthma were analyzed retrospectively. Results The patients were diagnosed with asthma through bronchodilation test,skin prick tests,fractional exhaled nitric oxide (FeNO) and diagnostic treatment.The ratio of male to female cases was 1:5. The ventilation lung function of all patients was in normal range. The median time of misdiagnosis was 13.5(3-120) months. 41.6% of cases had dust mite positive skin prick test. The median value of FeNO was 32.75(18-54) ppb. The symptoms of all patients were relieved completely after standard treatment. Conclusion Palpatation may be a specific presentation of asthma characterized with eosinophilic airway inflammation which may be misdiagnosed as other diseases for a long time,especially in elder women. To improve the knowledge of this kind of atypical asthma,detailed medical history, experimental examinations and diagnostic treatment response are important to confirm the diagnosis in time.
