Table 2 Mean ± Standard deviation of all descriptors with p values for NSR and CHF subjects.

From: Complex Correlation Measure: a novel descriptor for Poincaré plot

  SD 1 SD 2 CCM
NSR 0.03 ± 0.02 0.19 ± 0.04 0.05 ± 0.03
CHF 0.04 ± 0.02 0.11 ± 0.06 0.14 ± 0.06
p value (ANOVA) 5.65E-4 5.04E-12 9.07E-14
  1. Mean ± Standard deviation of SD 1, SD 2 and CCM for normal sinus rhythm (NSR) and congestive heart failure (CHF) subjects. p value from ANOVA is given in the last row. Though SD 2 and CCM shows similar difference among the mean of two subject groups, the standard deviation of CCM is lower which concentrates the distribution of CCM values around mean comparing with that of SD 2. The p value obtained using ANOVA analysis for CCM (p = 9.07 × 10-14) found more significant than SD 1 and SD 2.
