利用SIMULA** 语言开发了一个离散仿真模型，再现了心脏内的电势变化，并模拟了ECG信号的产生。用于计算实验，目前的版本是写在FORTRAN IV十，因为较低的内存需求和安装在台式计算机上。然而，FORTRAN版本保存了所有重要的SIMULA方法，并使心脏传导系统的不同病理情况下，以一种比较容易的方式进行建模。该模型特别适用于研究心脏节律及其紊乱的项目。已经进行了大量这样的实验。本文简要介绍了模拟系统，特别注意的模型原理和程序结果的描述。对现有的心电图生成模型进行了比较，并给出了实验结果。外部验证的模型和优点，已通过传输到FORTRAN的SIMULA模型进行了讨论。
A discrete simulation model reproducing electropotential changes within the heart and imitating the generation of the ECG signal has been developed using the SIMULA** language. Used for computational experiments, the current version is writ ten in FORTRAN IV because of lower memory demands and for installation on a desk-top computer. However, the FORTRAN version saves all important SIMULA methodology and enables different pathological situations of the cardiac conduction system to be modeled in a comparatively easy way. The present ver sion of the model is especially suited for projects studying car diac rhythm and its disorders. A large set of such experiments has been performed. This paper concisely describes the simulated system with special attention devoted to a description of the model principles and program results. Comparison is made be tween existing models of electrocardiogram generation, and some experimental results are shown. External validation of the model and advantages that have been obtained by transmitting the SIMULA model into FORTRAN are also discussed.
