Abstract

By studying a mathematical model of the effects of brief current impulses on the oscillation of cardiac cells, we have simulated the phase transition curves of the oscillators. This has permitted discussions of the interactions of two coupled sinus oscillators and the periodic stimulation of one ventricular oscillator. The results have been compared with findings from the normal electrocardiogram and applied to explain the mechanisms of some arrhythmias.

摘要

通过研究短暂电流脉冲对心脏细胞振荡影响的数学模型，我们模拟了振荡器的相变曲线。这使得我们能够讨论两个耦合正弦振荡器的相互作用以及一个心室振荡器的周期性刺激。已将结果与正常心电图的结果进行比较，并用于解释某些心律失常的机制。
