To characterize the multifractal behavior of the beat to beat heart-period or RR fluctuations in fibromyalgia patients (FM) in comparison with healthy-matched subjects. Multifractral detrended fluctuation analysis (MDFA) was used to study multifractality in heartbeat times-series from 30 female heal...
