[Methodology for analysis of binary sequences in heart rate].
A qualitative and quantitative method for the description of heart rate variability is demonstrated. It is based on a symbolic coding of time series taken from heartbeat intervals and calculation of the value "entropy" as a measure for information. Entropy seems to be a propriate measure to gain insight into the temporal structure underlying the phenomenon of heart variability.
