Heart rate variability analysis during head-up tilt test predicts nitroglycerine-induced syncope
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...
متن کامل[Early heart rate increase does not predict the result of the head-up tilt test potentiated with nitroglycerin].
INTRODUCTION AND OBJECTIVES The magnitude of the change in heart rate during the first few minutes of the head-up tilt test has been used to predict the test's result. The aim of this study was to investigate whether the heart rate increase during the head-up tilt test potentiated with nitroglycerin is related to the development of syncope. PATIENTS AND METHOD The study included 158 consecuti...
متن کاملEffect of head up tilt on heart rate variability in males
Keywords: Head up tilt(HUT) Heart rate variability(HRV) Low frequency(LF) High frequency(HF) Original Article AIMS : Orthostatic stress is commonly utilized to evaluate the cardiovascular autonomic function. This is done mainly by Head Up Tilt (HUT) testing. The parameters which represent the cardiovascular autonomic function involved the Heart Rate Variability (HRV).HRV indices provide non-inv...
متن کاملEffects of mental task on heart rate variability during graded head-up tilt.
In this study, we used spectral analysis of heart rate variability (HRV) to estimate the changes in autonomic control in response to disparate stimuli produced by mental task and graded head-up tilting. The low frequency (LF) component of HRV provided a quantitative index of the sympathetic and parasympathetic (vagal) activities controlling the heart rate (HR), while the high frequency (HF) com...
متن کاملLong-term outcome of patients with asystole induced by head-up tilt test.
AIMS To analyse the long-term outcome of the largest reported cohort of patients presenting asystole during head-up tilt test. METHODS AND RESULTS Since 1990, 1322 patients with syncope of unknown origin have undergone tilt-table testing. Of those, 330 patients (24 X 9%) presented an abnormal response (syncope or pre-syncope). Furthermore, 58 of those patients (17 X 5%) suffered a period of a...
