Objective: To evidence the occurrence of hyperventilation syndrome in Chinese patients.
Method: Case report and literature review.
Result: Three cases with manifest hyperventilation syndrome were reported. The diagnosis was based on the presence of several suggestive complaints occurring in a context of stress, and the reproduction of the most important complaints by the hyperventilation provocation test. Organic diseases as a cause of the symptoms had been excluded. Breathing therapy reducing the tendency to hyperventilate by acquiring an abdominal breathing pattern, with slowing down of expiration, markedly reduced complaints in the three patients.
Conclusion: Hyperventilation syndrome occurs also in Chinese patients.
