Shortened head-up tilting test guided by systolic pressure reductions in neurocardiogenic syncope.
BACKGROUND Asymptomatic reductions in arterial pressure have been reported to occur before the onset of tilt-induced syncope. We investigated the predictive value of these reductions for a positive tilt result. METHODS AND RESULTS In a first study, 238 consecutive healthy subjects with unexplained syncope underwent a passive tilt table test. Finger systolic arterial pressure (SAP) recordings ...
متن کاملHead-up tilt test in complicated neurocardiogenic syncope in children.
To confirm the usefulness of head-up tilt test (HUT) in neurocardiogenic syncope (NCS) with complicating clinical features, retrospective analysis were done on 12 selected children. The age at onset was 12.7 +/- 1.9 (mean +/- SD) years. Associated clinical features were postoperative congenital heart disease (PO CHD) in 3, coexistent arrhythmia in 8 (persistent ventricular arrhythmia during exe...
متن کاملProvocation of neurocardiogenic syncope by clomipramine administration during the head-up tilt test in vasovagal syndrome.
OBJECTIVES We sought to test the hypothesis that activation of the serotonergic system in patients with vasovagal syndrome during the head-up tilt test provokes syncope. BACKGROUND Central serotonergic activation participates in the pathogenesis of neurocardiogenic syncope. Drugs increasing serotonin (5-HT) in the central nervous system have not been tested as drug challenges during the head-...
متن کاملHead up tilt test in the diagnosis of neurocardiogenic syncope in childhood and adolescence.
BACKGROUND Neurocardiogenic syncope (NCS) is a common paroxysmal disorder that is often misdiagnosed as a seizure disorder. Head up tilt test (HUTT) has been used to confirm this diagnosis. There is no data available of its use in children / adolescents from India. AIM To study the usefulness of the HUTT in children and adolescents with suspected NCS. SETTINGS AND DESIGN This was a part ret...
متن کاملUsefulness of head up tilt test in the diagnosis of neurocardiogenic syncope.
Sir, I read with interest the article published by Udani V et al, which is a retrospective and part prospective study, evaluating the usefulness of head up tilt test in the diagnosis of neurocardiogenic syncope. The authors have made a good attempt to analyze the significance of HUTT in ruling out other perturbing causes of syncope in children and adolescents such as seizure disorders and verti...
