Autonomic nervous system plays an integral role in homeostasis. Autonomic modulation can frequently be altered in patients with cardiac disorders as well as in patients with other critical illnesses or injuries. Assessment of heart rate variability is based on analysis of consecutive normal R-R intervals and may provide quantitative information on the modulation of cardiac vagal and sympathetic nerve input. The hypothesis that depressed heart rate variability may occur over a broad range of illness and injury, and may inversely correlated with disease severity and outcome has been tested in various clinical settings over the last decade. This article reviews recent literature concerning the potential clinical implications and limitations of heart rate variability assessment in general medicine.
自主神经系统在体内平衡中起着不可或缺的作用。在患有心脏疾病的患者以及患有其他严重疾病或损伤的患者中,自主神经调节常常会发生改变。心率变异性评估基于对连续正常R-R间期的分析,可提供有关心脏迷走神经和交感神经输入调节的定量信息。在过去十年中,已经在各种临床环境中对心率变异性降低可能发生在广泛的疾病和损伤中,并且可能与疾病严重程度和预后呈负相关这一假设进行了检验。本文综述了近期有关心率变异性评估在普通医学中的潜在临床意义和局限性的文献。
