Heart rate variability (HRV) is a measure of the beat-to-beat variations in heart rate. It is usually calculated by analyzing a time series of beat-to-beat intervals from the ECG. Various measures of heart rate variability have been proposed, which can be subdivided into time domain, frequency domain and non-linear measures. HRV is regarded as an indicator of the activity of autonomic regulation of circulatory function. HRV has considerable potential to assess the role of autonomic nervous system fluctuations in normal healthy individuals, in patients with various cardiovascular and noncardiovascular disorders and, in patients undergoing general anesthesia. HRV studies should enhance our understanding of physiological phenomena, perioperative cardiovascular changes, the actions of medications, and disease mechanisms.
心率变异性(HRV)是一种衡量心率逐搏变化的指标。它通常通过分析心电图中逐搏间期的时间序列来计算。已经提出了多种心率变异性的测量方法,这些方法可细分为时域、频域和非线性测量方法。HRV被视为循环功能自主调节活动的一个指标。HRV在评估自主神经系统波动在正常健康个体、各种心血管和非心血管疾病患者以及接受全身麻醉患者中的作用方面具有相当大的潜力。HRV研究应能增强我们对生理现象、围手术期心血管变化、药物作用和疾病机制的理解。
