摘要：
A new index is proposed to estimate the variance of the differentiated heart rate (RR) time series from its truncated histogram, The index is more robust to artifacts than the standard deviation of the differentiated RR time series (rMSDD) and, unlike the pNN50, does not saturate for very high or very low heart rate variability.
