The simulation of excitation propagation's process in human heart is one of the main aspects of ECG forward problem. The simulation results not only are the criterion of the simulation model's precision and reliability, but also have great value in researches and diagnoses. We performed the simulation of QRST waves of complete left bundle branch block (LBBB) and right bundle branch block (RBBB) in virtue of a vector propagation algorithm (VPA), which is accurate, efficient and applicable to anisotropic computer heart models. The simulation results accord with the actual QRST wave in clinical practice.
人体心脏中兴奋传播过程的模拟是心电图正向问题的主要方面之一。模拟结果不仅是模拟模型精度和可靠性的标准，而且在研究和诊断中具有重要价值。我们借助一种矢量传播算法（VPA）对完全性左束支传导阻滞（LBBB）和右束支传导阻滞（RBBB）的QRST波进行了模拟，该算法准确、高效且适用于各向异性计算机心脏模型。模拟结果与临床实际的QRST波相符。
