摘要：
The results of numerical experiments on the one-dimensional, two-parameter circle map for heartbeats are reported and the global behavior of the Lyapunov exponent spectrum is presented. The results demonstrate chaotic dynamics in a mathematical model in which the normal sinus rhythm interacts with an ectopic pacemaker. Interestingly, structured behavior of the Lyapunov exponent spectrum is observed as the system follows the intermittency route to chaos.
