age and the head-up tilt test outcome in syncope patients
conclusions hemodynamic response to the hutt was associated with age. cardioinhibitory response became less frequent with age due to exaggerated vagal activity in the younger patients as compared with the older subjects. background the head-up tilt test (hutt) is a useful diagnostic tool for syncope. objectives we sought to investigate the outcome of the hutt in syncope patients and identify th...
متن کاملPredictors of response to the head-up tilt test in patients with unexplained syncope or presyncope.
BACKGROUND Unexplained syncope is a relatively frequent symptom, mostly caused by a neurocardiogenic reaction. The purpose of this study was to determine predictors of response to head-up tilt testing (HUTT) in patients with unexplained syncope or presyncope.

متن کاملDiagnostic value of the head-up tilt test and the R-test in patients with syncope
The diagnostic value of the head-up tilt test (HUTT) in discovering vasovagal syndrome depends on the pre-test probability. An accurate anamnesis and clinical examination screens the patients indicated for the HUTT. In patients with unexplained syncope, the R-test is an alternative procedure to discover its cause. In our study, we evaluated the diagnostic significance of the HUTT in a group of ...
