Methods A retrospective study of children who had tilt test between January 1997 and December 2001 in two cardiac centres using case notes and telephonic questionnaires. Results 111 children aged 6 to 18 years underwent tilt test, amongst them 81 were referred with history suggestive of vaso-vagal...
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 ...
Although the mechanisms by which upright posture triggersvasovagalfaints remains only incompletely understood, the head-up tilt table test has become the laboratory technique of choice for unmasking susceptibility to the vasovagal faint in patients with unexplained syncope. In this setting,tilt table tes...

Thirty patients with recurrent unexplained syncope were evaluated by use of an upright tilt table test for 30 minutes, with or without an infusion of isoproterenol (1 to 3 渭g/min given intravenously), in an attempt to produce hypotension, bradycardia, or both. There were 15 males and 15 ...
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 ...
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...

(38) In these cases, the alternating cover test typically reveals a vertical deviation that will increase in contralateral gaze, reduce in ipsilateral gaze, increase on ipsilateral head tilt and decrease on contralateral head tilt. Seeing double: assessing patients presenting with diplopia --B: head...
We also incorporated standing test in the protocol because of its practicality in places where a tilt table is not available. The aim of the study was to investigate the usefulness of standing and 80° tilt in a non-invasive protocol for orthostatic stress testing in children....
