We have performed an extreme value analysis of the heart beat fluctuations. We have analyzed 24-h ECG time series: by considering both, the RR intervals and the increments series ∆RR. Sub-series, corresponding to 5-h sleeping activity and to 5-h daily activity have been also separately studied. Strong differences are found in the mean return times for high thresholds of healthy and non-healthy patients, during both daily and sleeping activity.

Abstract
We have performed an extreme value analysis of the heart beat fluctuations. We have analyzed 24-h ECG time series: by considering both, the RR intervals and the increments series ∆RR. Sub-series, corresponding to 5-h sleeping activity and to 5-h daily activity have been also separately studied. Strong differences are found in the mean return times for high thresholds of healthy and non-healthy patients, during both daily and sleeping activity.File in questo prodotto:
