Head-up tilt for the evaluation of syncope of unknown origin in children.
نویسندگان
چکیده
Fifteen patients aged 10 to 18 years with syncope of unknown origin, and 10 healthy control children aged 11 to 18 years, were evaluated by head-up tilt to 60 degrees for 60 minutes. Six patients (43%) reproduced symptoms of syncope during the examination. Four had a typical vasovagal reaction; two had marked hyperventilation. None of the children in the control group had syncope. The head-up tilt test offers a simple, noninvasive, high-yielding diagnostic tool for evaluation of syncope in children.

Head-up Tilt Test with Isoproterenol Provocation in Syncope of Unknown Origin
OBJECTIVES Head-up tilt test (HUT) has been reported to be useful in the evaluation of syncope of unknown origin (SUO). However, the sensitivity of HUT with no pharmacologic provocation was relatively low and variable, ranging 32 approximately 70%. Therefore, several protocols of HUT with different degrees and durations of the tilt and modes of provocation were proposed. The purpose of this stu...
متن کاملThe Utility of Head Up Tilt Test with Video Electroencephalography in Children with Recurrent Loss of Consciousness
Aim: We aimed to detect the utility of head up tilt test with video electroencephalography (EEG) in children with unexplained, recurrent loss of consciousness episodes. Method: Video EEG were recorded during the head up tilt test. The test was terminated if syncope or presyncope with 30% decrease in heart rate and/or systolic blood pressure occurred. Regarding encephalography, average amplitude...

متن کاملClinical usefulness of head-up tilt test in patients with syncope and intraventricular conduction defect.
Head-up tilt test was performed in 99 patients with syncope of unknown origin and intraventricular conduction defect. Twenty-five per cent had a positive response to tilt with reproduction of spontaneous clinical symptoms. Holter recording revealed paroxysmal atrioventricular (AV) block in three patients. Carotid sinus massage was positive in four patients. An electrophysiological study was per...
