[The hyperventilation syndrome in children].

Hyperventilation syndrome is not a rare disorder present primarily in children, but in adolescents too. It points to anxiety in children with or without family problems. The clinical picture is polymorphous and often without a clear connection with hyperventilation. That is why it is necessary for the physician to be aware of this problem in practice. The diagnosis is made on the basis of clinical picture and hyperventilation provocative test, when one expects this disorder might occur. We have reported five cases of children with this syndrome, with a special review concerning clinical picture and the way which led to the confirmation of diagnosis.
