Key result
Distribution entropy (DistEn) demonstrated superior stability, consistency, and classification performance (median AUC 0.92 for arrhythmia detection) compared to approximate and sample entropy for analyzing short-length heart rate variability signals.
Why the study?
Does Distribution Entropy (DistEn) improve the classification performance and stability of analyzing short length HRV signals compared to ApEn and SampEn?
Does Distribution Entropy (DistEn) improve the classification performance and stability of analyzing short length HRV signals compared to ApEn and SampEn?
Distribution entropy (DistEn) is a more stable and consistent measure than approximate or sample entropy for analyzing short-length heart rate variability time series.

DistEn may enhance arrhythmia detection from brief HRV recordings; leaves open prospective validation before clinical use.
Karmakar et al. (2017) studied Heart rate variability (Aging and Arrhythmia) (n=105). Distribution Entropy (DistEn) vs. Approximate Entropy (ApEn) and Sample Entropy (SampEn) was evaluated on Classification performance (Area Under the ROC Curve, AUC) for distinguishing physiological and pathological conditions. Distribution entropy (DistEn) demonstrated superior stability, consistency, and classification performance (median AUC 0.92 for arrhythmia detection) compared to approximate and sample entropy for analyzing short-length heart rate variability signals.
