RHRV (version 2.4)

CalculateApEn: Calculates Approximate Entropy

Description

Calculates Approximate Entropy as indicated by Pincus

Usage

CalculateApEn(HRVData, indexNonLinearAnalysis = -1, m = 2, tau = 1, r = 0.2, N = 1000, verbose=FALSE)

Arguments

HRVData

Data structure that stores the beats register and information related to it

indexNonLinearAnalysis

Reference to the data structure that will contain the non linear analysis

m

Value of the dimension of the expansion of data

tau

Delay of the expansion of data

r

Distance for calculating correlation

N

Number of points of the portion of signal to be analyzed

verbose

Deprecated argument maintained for compatibility, use SetVerbose() instead

Value

• Returns HRVData, the structure that contains beat positions register and now associated heart rate instantaneous values also, including the value of the Approximate Entropy
