The difference between two points in time or two conditions in heart rate expressed as the ratio of the low frequency R-R interval component of the power spectrum analysis to the high frequency R-R interval component of the power spectrum analysis, expressed as the result of the subtraction in and of itself without comparison by ratio with another quantity.
The term "absolute change" refers to the subtraction of one value from another, as opposed to a dissimilarity of two values expressed as a ratio or as a percentage. In this context it is not intended to necessarily imply the difference expressed as an absolute value |n|, that is, the numeric value of the difference without regard to its sign.
