We exploited time irreversibility analysis to characterize short heart period sequences (256 samples) derived from 24h Holter recordings in normal healthy (NO) subjects and chronic heart failure (CHF) patients. We found a significant presence of irreversible dynamics over short time scales, whereas over dominant, longer time scales irreversibility was marginal. Over short time scales in NO subjects...
