BACKGROUND The head-up tilt test (HUTT) is a useful diagnostic tool for syncope. OBJECTIVES We sought to investigate the outcome of the HUTT in syncope patients and identify the relationship between age and different hemodynamic outcomes. PATIENTS AND METHODS In this cross-sectional study, we prospectively enrolled consecutive patients who presented with syncope and underwent the HUTT with ...

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...

PURPOSE It is estimated that approximately 20-30% of patients diagnosed with epilepsy have been misdiagnosed, and neurocardiogenic syncope (NCS) might frequently be the real cause of transient loss of consciousness (TLOC) episodes. We assessed the role of the head-up tilt test (HUTT) in patients previously diagnosed with refractory epilepsy to evaluate the ability of this test to correctly diag...

BACKGROUND The mechanisms under neurally mediated syncope (NMS) are not fully understood. This study aimed to assess the level of storage iron in children with different hemodynamic patterns in head-up tilt test. METHODS Altogether 210 children (11.31±2.49 years) with syncope or pre-syncope treated between May 2008 and September 2010 were studied prospectively. Following history taking and ph...

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...

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...

BACKGROUND Unexplained syncope is a relatively frequent symptom, mostly caused by a neurocardiogenic reaction. The purpose of this study was to determine predictors of response to head-up tilt testing (HUTT) in patients with unexplained syncope or presyncope. METHODS HUTT was done in 640 consecutive patients with unexplained syncope or presyncope (393 men, mean age 45+/-19 years) after initia...

Forty patients with recurrent syncopal episodes of uncertain etiology were evaluated with a 60-degree head-up tilt table test for 60 minutes. There were 21 men and 19 women, with a mean age of 36 +/- 19 years, a mean of 7.6 syncopal episodes per patient, and a mean duration of symptoms of 4.2 +/- 6 years. Twelve patients had evidence of organic heart disease. Ten control subjects with no histor...

OBJECTIVE The aim of this study was to determine whether or not heart rate variability (HRV) analysis during the first 20 min of head-up tilt testing could predict whether patients will develop syncope after nitroglycerine administration. DESIGN 64 patients with previous loss of consciousness underwent head-up tilt testing with the Italian protocol, which involves the administration of nitrog...
