Heart rate and blood pressure variability in subjects with vasovagal syncope.
Autonomic nervous system control in subjects with vasovagal syncope is controversial. In the present study, we used short-term spectral analysis to evaluate autonomic control in subjects with recurrent vasovagal syncope. We assessed the ability of spectral indices of HR (heart rate) variability to predict tilt-test responses. A series of 47 outpatients with recurrent vasovagal syncope and with ...
متن کاملHeart rate and blood pressure variability in orthostatic syncope.
The pathogenetic role of autonomic nervous system in the neurally mediated orthostatic vasodepressive syncope is unclear. upright tilt was used to assess the characteristics of autonomic tone during orthostatic stress. We studied 18 patients (mean age 26 +/- 5 years) suffering from vasodepressive orthostatic syncope and with positive response to a 30-minute 60 degrees upright tilt and a compara...
متن کاملPrediction of vasovagal syncope from heart rate and blood pressure trend and variability: experience in 1,155 patients.
BACKGROUND Vasovagal syncope (VVS) is a complex fainting disorder commonly triggered by orthostatic stress. OBJECTIVE We developed an algorithm for VVS prediction based on the joint assessment of RR interval (RR) and systolic blood pressure (SBP). METHODS Simultaneous analysis of RR and SBP trends during head-up tilt as well as their variability represented by low-frequency power (LFRR and ...
متن کاملWavelet Analysis of Blood Pressure Waves in Vasovagal Syncope
We describe the multiresolution wavelet analysis of blood pressure waves in vasovagal-syncope affected patients compared with healthy people. We argue that there exist discriminating criteria which allow us to isolate particular features, common to syncope-affected patients sample, indicating a tentative, alternative diagnosis methodology for this syndrome. We perform a throughout analysis both...
