This Diagnostic Test Interpretation uses a patient case to illustrate tilt table testing, useful for evaluating patients with syncope of unknown cause or postural orthostatic tachycardia syndrome (POTS).JAMA: Journal of the American Medical AssociationCheshire, William P.Dudenkov, Daniel V.Munipalli, ...
However, the interpretation of HUT requires care and experience; in particular, the outcome must be consistent with the patient's clinical presentation. The reproduction of patient symptoms may not only provide adiagnosis, but also offer some comfort to the patient and family in that the medical ...
Cerebral blood flow Head-up tilt table test Healthy volunteers Internal carotid artery blood flow Vertebral artery blood flow PetCO2 1. Introduction Positional changes from supine to sitting or standing result in a decrease of cerebral blood flow (CBF) as demonstrated by different techniques (Yoshimot...
Possible interpretation of tilt test results Our results suggest that patients with TT-induced reflex syncope may have increased resting vagal tone and/or lower sympathetic tone, both expressed by lower HR, and narrower hemodynamic margins in the face of orthostatic stress, expressed by lower initial...
The paper presents a comparison of vasovagal syndrome occurrence in a head up tilt table test between patients with a positive result of passive tilt test and those with a positive result after pharmacological provocation. The study group consisted of 80
Testing using the head-up tilt table is performed regularly as a diagnostic tool in the evaluation of syncope. Recommendations for protocols, and interpretation of the results, however, are mainly based on experience in adults. We evaluated the results of tilt table testing in 100 consecutive chil...

~8.1 Å (restored vs. ideal for ±60°) (Supplementary Table 2), which are even better than the ideal resolution (since the ideal map contains noise). The above tests suggest that by reducing the noise, the missing-wedge restorability can be improved. We want to test whether the ...
