Nonlinear Dynamics of Pulse Coupled Oscillators

心脏起搏器系统的数学模型将建立在简单的相互作用单元的基础上。这些单位已被证明是生理信息的良好模型，例如区分对心率的不同影响。我们将首先在简单组合中查看单元的相互作用，然后调整模型以模仿心脏起搏器的行为。

A mathematical model of the heart pacemaker system will be created, based on simple interacting units. These units have been shown to be good models of physiological information e.g. the discrimination of different influences on heart rate. We will firstly look at the interaction of the units in simple combinations and then tune the model to mimic the behaviour of the cardiac pacemaker. Potential benefits may arise from elucidating the mechanisms underlying arrhythmias which contribute to ?sudden cardiac death? in young men, and suggesting strategies for artificial pacemakers to effectively arrest abnormal rhythms before they convert to potentially fatal fibrillation.
