Cerebral blood flow during supine rest and the first minute of head-up tilt in patients with orthostatic intolerance.
AIM To assess the cerebral blood flow velocity during the first minute of head-up tilt in patients with postural tachycardia syndrome (POTS) or neurally-mediated reflex syncope compared with patients with dizziness. METHODS We evaluated 120 patients selected from 470 patients who underwent head-up tilt testing: 40 with POTS, 40 with typical neurally-mediated reflex syncope and 40 who complain...
متن کاملShort duration head-up tilt test: a comparison with conventional long protocol in patients of orthostatic intolerance.
BACKGROUND Orthostatic intolerance is development of symptoms during upright standing relieved by recumbency. An individual's predisposition to orthostatic intolerance (development of symptoms during upright posture) can be identified by Head-up Tilt Test (HUT). The aim of the present study was to compare the diagnostic yield (Percentage of patients tested positive) of short duration with conve...
متن کاملTemporal Artery Flow Response during the Last Minute of a Head Up Tilt Test, in Relation with Orthostatic Intolerance after a 60 Day Head-Down Bedrest
OBJECTIVE Check if the Temporal flow response to Tilt could provide early hemodynamic pattern in the minutes preceding a syncope during the Tilt test performed after a 60-d head down bedrest (HDBR). METHOD Twenty-one men divided into 3 groups [Control (Con), Resistive Vibration (RVE) and Chinese Herb (Herb)] underwent a 60 day HDBR. Pre and Post HDBR a 20 min Tilt identified Finishers (F) and...
متن کاملThe fainting patient: value of the head-upright tilt-table test in adult patients with orthostatic intolerance.
The head-upright tilt-table (HUT) test is used primarily for the investigation of orthostatic symptoms. Although this test is frequently the gold standard for the evaluation of neurocardiogenic syncope, dysautonomia and postural orthostatic tachycardia syndrome, there is a debate over its diagnostic value and method. The authors review the physiologic basis of the HUT test, the method, patterns...
متن کاملHemodynamic changes of unexplained syncope patients in head-up tilt test.
The purpose of this study was to observe the hemodynamic changes of unexplained syncope patients in the head-up tilt test and their correlations with age and gender. Eighty-six patients with unexplained syncope were administered the basic head-up test and nitroglycerin provocation test with continuous monitoring and recording of electrocardiogram and blood pressure changes. Basic characteristic...
