A procedure was proposed for non-invasive mapping of the cardiac electrical potential or a spherical quasiepicardium from its synchronous multichannel measurement on the surface of the chest, i.e. routine electrocardiodraphic mapping. Mathematical simulation was used to demonstrate that the quasiepicardial potential can be calculated with the accuracy sufficient for clinical diagnosis by applying the multipole electric field resolution method with allowance made for three lowest resolution terms. Due to the fact that the spherical quasiepicardium is more approximate to the heart and more concentric as to its center than the chest surface, the maps of the quasiepicardial potential permit recognition of some features of the pattern of a cardiac electric process, which do not manifest themselves in the distribution of the potential on the body's surface. The examples showing that the assessment of a cardiac abnormality can be made more accurate by using this method are given in the paper.
提出了一种从胸部表面同步多通道测量无创绘制心脏电位或球形准心外膜电位的方法，即常规心电图测绘。利用数学模拟证明，通过应用多极电场分辨率方法并考虑三个最低分辨率项，可以以足够用于临床诊断的精度计算准心外膜电位。由于球形准心外膜比胸部表面更接近心脏且其中心更同心，准心外膜电位图允许识别心脏电过程模式的一些特征，这些特征在体表电位分布中未表现出来。本文给出了表明使用该方法可使心脏异常评估更准确的实例。
