Measurements related to Phase Rectified Signal Averaging (PRSA) in time domain Heart Rate Variability analysis
4 variables.
-
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
x0ec229DC
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

ACmod: modified Acceleration Capacity, computed according to the formula given in Nasario-Junior et al. 2014, expressed in milliseconds
x0ec231DCmod
DCmod: modified Deceleration Capacity, computed according to the formula given in Nasario-Junior et al. 2014, expressed in milliseconds
