Heart rate variability (HRV) non-invasively assesses the activity of the autonomic nervous system. During the past 30 years, an increasing number of studies have related the imbalance of the autonomic nervous system (as assessed by HRV) to several pathophysiogical conditions, particularly in the setting of cardiovascular disease. Sudden death, coronary artery disease, heart failure, or merely cardiovascular risk factors (smoking, diabetes, hyperlipidemia, and hypertension) are the best-known clinical circumstances that can affect and/or be affected by the autonomic nervous system. Analyses of HRV variables have been proposed as a component of the clinical evaluation for patient risk stratification due to its independent prognostic information. Yet the potential for HRV to be used widely in clinical practice remains to be established.
心率变异性（HRV）可无创评估自主神经系统的活动。在过去的 30 年中，越来越多的研究将自主神经系统失衡（通过 HRV 评估）与多种病理生理状况相关联，尤其是在心血管疾病的情况下。猝死、冠状动脉疾病、心力衰竭，或仅仅是心血管危险因素（吸烟、糖尿病、高脂血症和高血压）是影响和/或受自主神经系统影响的最常见临床情况。由于其具有独立的预后信息，因此 HRV 变量分析已被提议作为患者风险分层临床评估的一个组成部分。然而，HRV 在临床实践中的广泛应用潜力仍有待确定。
