Effect of patient characteristics on the yield of prolonged baseline head-up tilt testing and the additional yield of drug provocation.
OBJECTIVE To define the value of tilt testing and hte additional yield of drug provocation over prolonged baseline tilt in different patient subgroups. (Many different protocols are in use for head-up tilt testing in heterogeneous groups of patients. Not all patients in reported series have recurrent syncope, and there is often a wide age range and a variable incidence of structural heart disea...
متن کاملHead-up tilt testing in children.
The article by Kouakam et al. in issue 22/17 is a prospective observational study of syncope recurrence in 101 children (mean age 12·6 3; range 7–18 years) undergoing head-up tilt testing for investigation of recurrent unexplained syncope or presyncope. Data are presented for patients recruited between 1990 and 1998, and followed-up for an average of 4 years. Head-up tilt was initially positive...
متن کاملHead-up tilt test with clomipramine challenge in vasovagal syndrome--a new tilt testing protocol.
PURPOSE The aim of the study was to randomly compare clomipramine, used as a challenge-agent during head-up tilt test, with isoproterenol, used in the conventional test, in patients with vasovagal syndrome. SUBJECTS AND METHODS The serotonergic re-uptake inhibitor clomipramine was infused (5mg in 5min) at the start of head-up tilt test (Clom-HUT) in 126 patients (mean age 41+/-16 years) with ...
متن کاملThe normal response to prolonged passive head up tilt testing.
OBJECTIVE To define the responses to head up tilt in a large group of normal adult subjects using the most widely employed protocol for tilt testing. METHODS 127 normal subjects aged 19-88 years (mean (SD), 49 (20) years) without a previous history of syncope underwent tilt testing at 60 degrees for 45 minutes or until syncope intervened. Blood pressure monitoring was performed with digital p...
متن کاملPrior head-down tilt does not impair the cerebrovascular response to head-up tilt.
The hypothesis that cerebrovascular autoregulation was not impaired during head-up tilt (HUT) that followed brief exposures to varying degrees of prior head-down tilt (HDT) was tested in 10 healthy young men and women. Cerebral mean flow velocity (MFV) and cardiovascular responses were measured in transitions to a 60-s period of 75° HUT that followed supine rest (control) or 15 s HDT at -10°, -...
