| Abstract: | Under the acceptable hypothesis that cardiac rhythm is an approximately deterministic process with a small scale noise component,
an available way is provided to construct a model that can reflect its prominent dynamics of the deterministic component.
When applied to the analysis of 19 heart rate data sets, three main findings are stated. The obtained model can reflect prominent
dynamics of the deterministic component of cardiac rhythm; Cardiac chaos is stated in a reliable way; Dynamical noise plays
an important role to the generation of complex cardiac rhythm. |
