The head-up tilt table test is a way to find the cause offaintingspells. You lie on a bed and you’re tilted at different angles (from 30 to 60 degrees) while machines monitor yourblood pressure, electrical impulses in yourheart, and oxygen level. It’s done in a special room called ...
'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...
HEAD-UP TILT TABLE TESTING FOR ASSESSING SUSCEPTIBILITY TO VASOVAGAL SYNCOPE Although the mechanisms by which upright posture triggers vasovagal faints remains only incompletely understood, the head-up tilt table test has become the laboratory technique of choice for unmasking susceptibility to the vasovag...

tilt table testingRecurrent idiopathic vertigo associated with near-syncope and syncope is a common perplexing problem, some cases of which are considered autonomically mediated (vasovagal). Upright-tilt-table testing has emerged as a potential method to test for vasovagal episodes. This study ...
Head-up tilt table testing was performed in 50 patients for evaluation of syncope. A positive test occurred in 29 patients (58 percent). Of these 29 patients, 15 were categorized as vasovagal; 11 as orthostatic hypotension; and three as chronotropic incompetence. Isoproterenol facilitated the occur...
(45.67%)and more common in adults and in baseline head-up tilt table test(BHUT).Sinoatrial bradycardia was familiar(53/58)and often accompanied by junctional escape rhythm,junctional escape and asystole.The averaged time of asystole in 10 cases was(12.68±17.94)s.Basic heart rates were slower ...
Syncope occurred in nine patients (36%) during the baseline tilt and in seven patients (28%) during isoproterenol infusion (total positives 64%). None of the controls had syncope during the test. All of the patients who had positive test results eventually became tilt table negative with ...
The influence of sex and age on response to head-up tilt-table testing in patients with recurrent syncope. Syncope is a common problem, accounting for 6% of hospital admissions. Often a diagnosis is not established. Head-up tilt testing is a diagnostic test for ... A,D,McGavigan,... -...
