目的　构建基于正常心脏数据的三维动态心脏模型。  方法　采集正常成人心脏数据，通过Microsoft Visual C++和3DMax软件重建生成心脏三维模型，并将正常心电图与之整合，同步显示心脏运动。  结果　建立了数字化心脏可视动态模型，能够反映心脏三维形状和内腔结构，并可与心电图同步运动。  结论　动态心脏模型能够为心脏结构与运动的教学及疾病分析提供可视化的数值仿真平台。

Objective　To construct three dimensional dynamic heart model based on the anatomic data of normal heart.　Methods　Anatomic data of normal heart were collected for reconstructing three dimensional dynamic heart model by Microsoft Visual C++ and 3DMax software, as well, the normal electrocardiogram (ECG) was integrated with heart model to demonstrate heart activity synchronously.　Results　The digital heart model was constructed, which reflected the shape and internal structures of the heart. Synchronous activity of ECG could be performed on heart model.　Conclusions　As a digital platform, the dynamic heart model is a valuable tool for anatomic teaching and heart disease analysis.
