In this article, we develop a nonparametric method, called adjusted exponentially tilted (ET) likelihood, and apply it to the analysis of morphometric measures. The adjusted exponential tilting estimator is shown to have the same first-order asymptotic properties as that of the original ET likelihood. The adjusted ET likelihood ratio statistic is applied to test linear hypotheses of unknown par...

PURPOSE To investigate the diagnostic yield of different tests and asses the scope of causes in children referring to the hospital with a syncope in north-eastern Poland. METHODS A review of 386 consecutive patients (age 2-18 years) living in north-eastern Poland presenting to the cardiology department with a new onset syncope (which appeared to be neurally mediated by history) was undertaken...

OBJECTIVES Endoscopic transthoracic sympathicotomy (ETS) is a minimal invasive procedure of thoracic sympathetic blockage. The purpose of this study was to evaluate cardiac autonomic nervous activity after ETS in order to confirm the reliability and safety of ETS. METHODS A series of electrophysiological studies were performed before and 1 week after bilateral 2nd and 3rd thoracic sympathicot...

OBJECTIVES This study was conducted to develop a time-efficient tilt table test. BACKGROUND Current protocols of tilt table testing are quite time-consuming. This study was designed to assess the diagnostic value, tolerance and procedural time of a single-stage isoproterenol tilt table protocol. METHODS A single-stage isoproterenol tilt table test was compared with the passive tilt table te...

Changes in hemodynamic parameters following 50-degree head-up tilt were studied in a population of 56 men, including 35 subjects with sustained essential hypertension and 21 agematched normotensive controls. The increase in heart rate following tilt was similar in both groups and exhibited the same reduction in response with age. The increase in vascular resistance following tilt was strongly a...

INTRODUCTION Syncope is a common problem and can lead to serious consequences in the elderly. Tilt test is useful to investigate recurrent syncope, but few studies have investigated the hemodynamic responses of this population to tilt test. OBJECTIVE To describe the tilt test responses of elderly patients with recurrent syncope of unknown origin and to determine the occurrence of altered card...
