Abstract:
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.
