Through the simulation based on a two-dimensional whole-heart electrophysiological model the effect of ventricular electrical activity on the precordial cardioelectrical field as well as the ECG manifestation have been discussed. Such effect can vary with the changed excitation sequence of ventricles and the changed active and passive electrical properties of cardiac tissues. As the result many abnormal ECG waves can form.

Through the simulation based on a two-dimensional whole-heart electrophysiological model the effect of ventricular electrical activity on the precordial cardioelectrical field as well as the ECG manifestation have been discussed. Such effect can vary with the changed excitation sequence of ventricles and the changed active and passive electrical properties of cardiac tissues. As the result many abnormal ECG waves can form. By carefully analyzing such effect the correlation among ECG waveforms recorded at different lead locations can be revealed and the significance of ECG manifestation can be fully explored. As a case of analyzing some ECG waves at certain right chest lead locations can get a proper explanation.

通过基于二维全心脏电生理模型的仿真,揭示了心室电活动对同侧及对侧胸表心电场的影响及其心电图表现,这种影响可因心室兴奋时序的变化以及室壁心肌组织主动与被动电学性质的变化而发生改变,由此产生多种心电图波形的变异。通过对这种影响进行分析,不同导联间心电图波形的关联性能够得到识别,其临床意义得到充分揭示。作为例子,我们对某些右胸导联心电图波形进行了解释。

In this paper, based on the whole-heart electrophysiological model we built and the ECG computing algorithm we presented that computes ECG baesd on the action potential of interconnected and intercommunicated cardiac cells, we introduce the description method of abnormal cardioelectrical activity, give the simulation results of some abnormal ECGs, and explain the generation mechanism of these abnormal ECGs. The simulated ECG, introding local myocardial ischemia,myocardial infarction, atrium-ventricle conduction block, left bundle branch conduction block, right bundle branch conduction block, and atrium-ventricle bypass, highly accord with clinical recordings. The algorithm and the simulation results show that it is the transjunctional gradient of membrane potential between cells that contributes to the formation of field potential and ECG waveforms. We believe that the generation of all normal and abnormal ECGs can be reasonably explained with this mechanism.
