摘要
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。
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．
