全心脏电生理模型的仿真应用

Simulation Application of Whole-heart Electrophysiological Model

实现了用细胞自动机式并行计算构造全心脏的电生理模型 ,并介绍这种电生理模型的仿真设施与应用。仿真应用首先是求解心电图正问题 ,尤其是仿真各种心律失常心电图 ,准确说明各种不规则波形所蕴含的电生理意义。其次 ,是在通道层次对心电活动动力学性质特别是对心律失常形成与维持的机制进行研究。第三 ,是模拟对心电活动的各种调制与干预 ,研究起搏、除颤、消融。

An efficiently approach to building whole-heart electrophysiological model with cellular automata style massive parallel computing is realized. The simulation facilities of a model has been built and the potential application of such model is introduced. The first use is to solve the forward problem of electrocardiogram. Simulating arrhythmia ECG and accurately interpreting the significance of various irregular waveforms will be the key goal. Investigating the dynamic property of cardioelectrical activity at cellular and channel levels is the second application, aiming at revealing the mechanism of the generation and sustentation of arrhythmia. Third, the model can be used to research the impacts of artificial interventions on cardioelectrical activity. Electrical defibrillation and pace-making as well as the use of channel block agents are all cases.
