Abstract :
Chaos is defined by means of an everyday example, and it is shown how chaos could be modeled using a one-dimensional second-order difference equation as used in population dynamics. A mathematical model for the perturbation of a biological oscillator either by single or periodic impulses is reported. The model could be used to explain certain forms of cardiac dysrhythmics by means of period-doubling bifurcations and chaotic dynamics
