Module Label Name Description Type
Heart rate variability (CHRIS baseline) x0ec267 EDR (ECG Derived Respiration) EDR (ECG Derived Respiration), expressed in Hz Float
Heart rate variability (CHRIS baseline) x0ec276 DFA alpha2 DFA alpha2: Detrended Fluctuation Analysis measures the correlation within the signal. Slope alpha2 characterizes long-term fluctuations or the RR series Float
Heart rate variability (CHRIS baseline) x0ec275 DFA alpha1 DFA alpha1: Detrended Fluctuation Analysis measures the correlation within the signal. Slope alpha1 characterizes short-term fluctuations or the RR series Float
Heart rate variability (CHRIS baseline) x0ec232 DCmod DCmod: modified Deceleration Capacity, computed according to the formula given in Nasario-Junior et al. 2014, expressed in milliseconds Float
Heart rate variability (CHRIS baseline) x0ec230 DC DC: Deceleration Capacity is a measure of cardiac parasympathetic modulation as it captures the lengthening of RR interval within 2-4 successive beats. It is computed as a four point difference from the deceleration PRSA signal (phase-rectified signal averaging), expressed in milliseconds Float
Heart rate variability (CHRIS baseline) x0ec274 Correlation Dimension D2 Correlation Dimension D2: it is a method for measuring the complexity or strangeness of the RR series. This index is expected to give information on the minimum number of dynamic variables needed to model the underlying system Float
Heart rate variability (CHRIS baseline) x0ec272 Approximate Entropy Approximate Entropy: measures the complexity or irregularity of the signal. Large values of ApEn indicate high irregularity and smaller values of ApEn more regular signal Float
Heart rate variability (CHRIS baseline) x0ec231 ACmod ACmod: modified Acceleration Capacity, computed according to the formula given in Nasario-Junior et al. 2014, expressed in milliseconds Float
Heart rate variability (CHRIS baseline) x0ec229 AC AC: Acceleration Capacity captures the shortening of RR interval within 2-4 successive beats. It is computed as a four point difference from the acceleration PRSA signal (phase-rectified signal averaging), expressed in milliseconds Float
