title: [Is the head-up tilt-test necessary in patients whit clinical diagnosis of vasovagal syncope? Results using a non-sensitized protocol].
abstract: BACKGROUND
  Tilt table testing is a simple, non-invasive, low risk test. A not sensitized protocol has been presented in order to shorten the duration of the test.
  
  
  OBJECTIVE
  To determine the usefulness of a not sensitized tilt table testing and to compare the results with the pre-test probability, given by the Calgary's score.
  
  
  METHODS
  We included patients≥15 years-old with syncope or presyncope with high probability pretest for a vasovagal origin, using the Calgary' score.
  
  
  RESULTS
  Seventy patients were analyzed; age 39±20 years old, 66% female. More than 94% of the patients presented a score≥-1, but only 30% of the tilt tests were positive. A score≥-2 was not associated with the result of tilt test. Most of the patients presented a score of 1 (52) and 2 (11), resulting in positive tilt test 32% y 9%, respectively. Among patients with low pre-test probability there was a greater number of negative results (100% with a score of -2 and 50% with score of -5).
  
  
  CONCLUSIONS
  This study showed that in patients with vasovagal syncope suggested by clinical assessment, a not sensitized tilt test did not provide additional information, with a significant number of false negatives.
