Multifractal‐Multiscale Analysis of Cardiovascular Signals: A DFA‐Based Characterization of Blood Pressure and Heart‐Rate Complexity by Gender
Key result
A novel DFA-based method applied to cardiovascular signals revealed that scale coefficients and multifractality depend on temporal scale, with significant sex differences in heart rate and blood pressure dynamics.

Lazzeroni et al. (2018) conducted an observational in Volunteers (n=84). Sex (female vs male) vs. Male volunteers was evaluated on Scale coefficients and degree of multifractality of interbeat intervals, systolic blood pressure, and diastolic blood pressure. A novel DFA-based method applied to cardiovascular signals revealed that scale coefficients and multifractality depend on temporal scale, with significant sex differences in heart rate and blood pressure dynamics.
