Heart Rate Variability (HRV) is the measure of time variation between heartbeats. For example, even if your heart rate is 60 beats per minute, it doesn’t beat exactly once per second. Instead, the time intervals between beats vary slightly, and this variability is what HRV measures. W...

心率变异性( Heart Rate Variability) ,简称HRV,是指个体连续心搏间瞬时心率的微小涨落。HRV信号蕴含了有关心血管调节的大量信息,对这些信息的提取和分析可以定量评估心脏交感神经和迷走神经活动的紧张性、均衡性及其对心血管系统活动的影响。 HRV分析使用的数据序列是从ECG心电或PPG脉搏信号中提取的搏动间隔的时间序列...
心率变异性(Heart Rate Variability,简称HRV),这个名词听起来可能稍微有点陌生,正如ESR和 CRP是感染性或炎症性疾病的敏感性指标一样,心率变异性或许是能够反映你最真实的身心健康状况的重要指标! 大量相对较老的相关文献将HRV的改变与创伤后应激障碍、睡眠障碍、抑郁、自主神经系统紊乱、各种心律失常、疲劳、过度劳累、...
这一期,我们讲心率变异性(Heartratevariablity),简称HRV。 【概要先行】 ①健康的心脏拥有健康的“不规律”,HRV测的就是心跳的不规律性。 ②心跳的不规律性是由自主神经主导的;因此,HRV能够反映神经系统的健康。 ③通常来说HRV越高越好。高HRV代表更好的心血管功能和抗压能力,而低HRV意味着更高的焦虑抑郁风险,...
Heart rate variability (HRV) seems to be on everyone’s lips these days, at least those who are interested in monitoring their own or their clients’ sleep, recovery, performance or overall health. The phenomenon itself is not new, but its use in everyday language and in widely available ...
