FISHER, J.D., et al.: Simplified Tilt Table Test Protocol with Continuous Upright Position During Medication Administration and No Hydration.Recommendations for head-up tilt testing (HUT) often include the prolonged abstaining from food and water consumption (nothing by mouth [NPO]) and intravenous...
The tilt-table test protocol at our hospital was standardized and consisted of upright tilt to 70[degrees] for 30 minutes followed by administration of either isoproteronol or single dose of sublingual nitroglycerin 0.4 mg if the test was negative after 30 minutes, with an additional 15 minute ...
If nothing happens, the table is returned to the flat position and an intravenous infusion of isoproternol (Trade name = Isuprel) is started. This medicine increases the HR and BP. This effect is similar to that produced by our own natural adrenaline release. As you may have gathered, t...
'Front-loaded' head-up tilt table testing: validation of a rapid first line nitrate-provoked tilt protocol for the diagnosis of vasovagal syncope. Head-up tilt testing is the investigation of choice in the diagnosis of vasovagal . The test is time consuming and labour intensive, with conventiona...

The authors hypothesize that there is a significant increase in the baroreceptor activity with a decrease in the sensitivity during the upright phase in comparison to the supine phases of the head upright tilt test (HUTT) protocol. Methods Baroreceptor evaluation was performed using the sequence ...
Key Words: Syncope; Orthostatic intolerance; Tilt table test; Hypotension; Bradycardia Core tip: A tilt table test (TTT) is a noninvasive tool for the differential diagnosis of syncope and orthostatic intolerance. The way of the response to the orthostatic challenge helps to differentiate between...
The findings of Fitzpatrick and colleagues12were instrumental in defining a practicable tilt test protocol. Subsequently, based primarily on the report by Almquist and associates13and later Natale and coworkers,14the angle of the table was increased in most laboratories to between 70 and 80 degrees...
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...
Table 1 Univariable and multivariable analysis of factors predicting tilt test positivity in patients investigated for unexplained syncope using the Italian tilt test protocol. Full size table Exclusion of one database did not substantially affect the overall results except for the impact of low SBP on...
