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.
本文展示了一种用于描述心率变异性的定性和定量方法。该方法基于对心跳间期时间序列的符号编码，并计算“熵”值作为信息度量。熵似乎是一种合适的度量，可用于深入了解心率变异性现象背后的时间结构。
