心血管心理生理学家经常将连续数据的变异性表示为均方连续差异的根。其他变异性参数，如标准差和变异系数，主要由缓慢（如昼夜节律）节律或线性趋势决定。当在增加的时间段内每小时计算血压数据的变异性参数时（以模拟在可变持续时间后血压监测的终止），标准偏差和变异系数由于晚上和夜间血压水平的降低而增加，但均方连续差异的根不增加。从147名门诊患者的10784个血压读数的数据中可以看出，使用均方连续差的根作为血压变异性的参数的优点。
Cardiovascular psychophysiologists often express variability in successive data as the root of the mean squared successive differences. Other parameters of variability, such as the standard deviation and the coefficient of variation, are largely determined by slow (such as circadian) rhythms or linear trends. When the parameters of variability in blood pressure data are calculated each hour over an increasing period of time (to simulate the termination of the blood pressure monitoring after a variable duration), standard deviations and coefficients of variation increase due to the decrease in blood pressure levels at evening and night, but the root of the mean squared successive differences does not. The advantage of using the root of the mean squared successive differences as a parameter of blood pressure variability is shown in data from 147 outpatients with 10784 blood pressure readings.
