你的心跳有多随机?
How random is your heart beat?
摘要:
我们测量心率变异性中随机不相关噪声的含量,使用粗粒度熵的噪声水平估计的一般方法。我们表明,通常-除了心房颤动-这种噪声的水平是在5 - 15%的数据的方差和变异性,由于线性相关的过程是占主导地位的所有情况下,但心房颤动的分析。心率变异性的非线性确定性内容仍然是重要的,不可忽视。
英文摘要:
We measure the content of random uncorrelated noise in heart rate variability using a general method of noise level estimation using a coarse grained entropy. We show that usually - except for atrial fibrillation - the level of such noise is within 5 - 15% of the variance of the data and that the variability due to the linearly correlated processes is dominant in all cases analysed but atrial fibrillation. The nonlinear deterministic content of heart rate variability remains significant and may not be ignored.
