HUTT was positive for syncope in 183 patients (53.04 %) and increase to 76.2 % if other diasutonomic disorders are added. Vasodepresor syncope was the most frequent (59 %) with statistically significant predominance, followed by mix response. Discussion: Syncope is a frequent medical atenndance cause and it causes parents anxiety. Our results are similar to other authors being vasodepresor syncope the most frequent.
