充血性心力衰竭患者心率变异性(HRV)减低,提示心脏自主神经功能受损及预后不良,已有研究提示经鼻腔持续气道正压(CPAP)可改善心力衰竭患者心率的神经调节和心脏功能。本文旨在了解短期经鼻腔CPAP对充血性心力衰竭患者HRV的影响。
Heart rate variability (HRV) decreased in patients with congestive heart failure, suggesting impaired cardiac autonomic function and poor prognosis. It has been suggested that continuous positive airway pressure (CPAP) in the nasal cavity can improve the heart rate in patients with heart failure, neuromodulation and cardiac function . This article aims to understand the impact of short-term nasal CPAP on HRV in patients with congestive heart failure.
