Impaired Baroreflex Gain in Patients with Inappropriate Sinus Tachycardia
Abstract
INTRODUCTION: The aim of this study was to determine the characteristics of heart rate variability (HRV), blood pressure variability (BPV), and baroreflex gain (BRG) at rest and during orthostatic stress in patients with clinical criteria of inappropriate sinus tachycardia (IST).
METHODS AND RESULTS: Beat-to-beat HRV and BPV, measured by time- and frequency-domain methods, and noninvasive BRG, calculated by cross-spectral analysis, were …
