[Diagnosis of neurogenic syncope--current views].
Neurocardiogenic syncope is a very common clinical problem and represents the most frequent cause of syncope. Its diagnosis is difficult because there are several and heterogeneous causes of syncope, that can interact each other, and the accuracy of the available diagnostic instruments is sometimes not high enough. For these reasons, the classification of a syncope as neurocardiogenic is the result of an evaluation, whose main purpose is the exclusion of the other possible causes of syncope with worse prognosis. The head tilt-up test is recommended for the diagnosis of the most frequent type of neurocardiogenic syncope, the vasovagal syncope. The methodological improvement of tilt test could, in the future, improve its diagnostic accuracy and could optimise the time of execution.
