The body surface electrocardiogram (ECG) is a direct result of electrical activity generated by the myocardium. Using the body surface ECGs to reconstruct cardiac electrical activity is called the inverse problem of electrocardiography. The method to solve the inverse problem depends on the chosen cardiac source model to describe cardiac electrical activity. In this paper, we describe the theoretical basis of two inverse methods based on the most commonly used cardiac source models: the epicardial potential model and the equivalent dipole layer model. We discuss similarities and differences in applicability, strengths and weaknesses and sketch a road towards improved inverse solutions by targeted use, sequential application or a combination of the two methods.
体表心电图（ECG）是心肌产生的电活动的直接结果。利用体表心电图重建心脏电活动被称为心电图反问题。解决反问题的方法取决于所选择的心脏源模型来描述心脏电活动。在本文中，我们描述了基于最常用的心脏源模型的两种反演方法的理论基础：心外膜电位模型和等效偶极层模型。我们讨论了它们在适用性、优缺点方面的异同，并勾勒出一条通过有针对性地使用、顺序应用或两种方法结合来改进反演解的途径。
