[Flatus gone astray and other causes of syncope ].

Loss of consciousness i.e. syncope is a common cause of getting to emergency call service. We describe two patients, in whom fainting was caused by reflexogenic syncope. The diagnosis is quickly solved if there is patience to review the patient history as thoroughly as possible. Registration of the conventional 12-lead electrocardiography and clinical examination usually suffice as basic investigations, without the need for expensive equipment. Careful scrutiny of the medical history will not only reveal the cause of fainting but also the predisposing factors, whereby recurrence of the event can easily be avoided by recognizing a threatening situation early enough.
