研究表明，神经激素的激活在充血性心力衰竭（ＣＨＦ）发生发展过程中起重要作用［１］。业已证明，心率变异性（ＨＲＶ）可作为一项反映自主神经对心脏调控的无创性指标［２］。作者分析４８例正常人及５２例ＣＨＦ患者ＨＲＶ变化规律，旨在了解ＣＨＦ患者的自主神经的活... Studies have shown that the activation of neurohormones in the development of congestive heart failure (CHF) play an important role [1]. It has been demonstrated that heart rate variability (HRV) can be used as a noninvasive indicator of cardiac regulation by autonomic nerves [2]. The author analyzes the changes of HRV in 48 normal subjects and 52 CHF patients to understand the autonomic activity of CHF patients.
