Abstract

We show that complex patterns of certain abnormal heartbeats in the normal heart rhythm can be described by a model of two independent oscillators with stochastic elements. We find that this model successfully reproduces key statistical properties of the abnormal beats within a 12-hour heartbeat record, and demonstrate how the noise accounts for the emergence of the patterns of normal and abnormal heartbeats. We observe a best agreement with the data when an `optimal' level of noise is introduced.
