Physical basis of SATRO - a new method for analysis of the cardiac muscle depolarisation
摘要：
基于电流流过单根纤维的模型，描述了心肌上电荷密度的变化。利用有关的解析公式，并结合数值计算，确定了胸腔表面电势的分布和时间依赖关系。所得结果与经验数据进行了比较。理论预测和实验数据之间有很强的相关性。所讨论的模型允许检查由心肌的特定段的电激活引起的瞬时电位。
英文摘要：
On the basis of the model of the current flow through a single fibre, changes in the electric charge density over the myocardium are described. With the use of relevant analytic formulae, supported with numerical calculations, the distribution and time dependencies of electric potentials on the surface of the thorax have been determined. The results obtained are compared with empirical data. A strong correlation between the theoretical predictions and the experimental data has been obtained. The model in question permits examination of instantaneous potentials resulting from electrical activation of particular segments of the cardiac muscle.
