[Selection and long-term effect of treatment in vasovagal neurocardiogenic syncope].
BACKGROUND
Syncope state performed by transient loss of consciousness connected with a postural tone decrease present still an important therapeutical problem. The authors use HUT testing for discovering of vasovagal etiology of a syncope. The aim of the study was to find out the optimal medication in treatment and prevention of VVS by repeated HUT drug testing in a group of positive patients.


RESULTS
We examined a group of 300 patients (172 female and 128 male) age 35.26 +/- 13.47 years with an anamnesis of recurrent syncopes by HUT test. In 83 patients (27%) we set up a diagnosis of VVS. Thirteen patients (15.66%) were only followed without medication. The rest of the group (70 patients, 84.34%) started with a therapy. Testing was performed by repeated HUT according to the "Westminster protocol". HF and BP were measured by FINAPRESS 2,300 made by Ohmeda. The effective therapy was found in 64 patients (91.43%) of the group. For various reasons the therapy was changed and retested in 9 patients (14.06%). Beta1 selective beta-blockers were used in 51 patients (80.96%) theophyllin in 5 patients (7.94%), etilephrin in 6 patients (9.52%) and clonidine in 1 patient (1.59%).


CONCLUSIONS
The therapy of VVS should be set-on according to the effective drug selection by serial drug testing in repeated HUT tests. The article shows a high predictive value of negative HUT test for a long term effect of tested therapy.
