Simultaneous Beat-To-Beat Heart Rate And Systolic Blood Pressure Variability In Patients With And Without Neurally Mediated Syncope

2021-06-08

Abstract excerpt

<h4>Background: </h4> Autonomic changes play an essential role in the genesis of neurally mediated syncope (NMS). The aim of this study was to compare the changes of the autonomic nervous system (ANS) by measuring spectral indices of beat-to-beat systolic blood pressure and heart rate variability (SBPV and HRV) in ranges of low frequency (LF), high frequency (HF), and the LF/HF ratio during head-up tilt test (HUTT...
