给出了心电向量投影概念的数学和物理基础，并讨论了它对当前额面和空间心电图实践的意义。理论基础的假设被陈述并被用来推导心脏偶极子和它在体内产生的电势之间的一般关系。给出了单极引线和双极引线以及威尔逊中心端电压的具体方程。系数确定。人体躯干模型的实验结果与埃因多芬的S假说有很大的不同。埃因霍芬的S等边三角形是一般理论的一个特例。几何解释被应用于一个定量的额面例子，威尔逊中心端电压，并扩展到与人体表面相对应的图像表面的概念。
A mathematical and physical basis for heart-vector projection concepts is presented and its significance for current practices in frontal-plane and spatial electrocardiography is discussed. Assumptions underlying the theory are stated and utilized to derive a general relationship between the heart dipole and the potentials it produces in the body. Specific equations are given for unipolar and bipolar leads and the Wilson central-terminal voltage. Coefficients detd. experimentally for human torso models differ markedly from those that stem from Einthoven''s hypothesis. Einthoven''s equilateral triangle represents a special case of the general theory. Geometric interpretations are applied to a quantitative frontal-plane example, to the Wilson central-terminal voltage and extended to the concept of an image surface corresponding to the human body surface.
