Few-lead Systems for Noninvasive Imaging of the Cardioelectric Field on a Standard Surface

The ECG body surface potential mapping (BSPM) has been completely mastered and is regularly applied in some large cardiology institutions; however, a more widespread use of this method has slowed down, primarily because of the expensiveness and labour-consuming nature of such diagnostical procedure. This paper presents some results of a comparative experimental investigation of two practicable systems, which provide for the body surface potential measurement with few-electrode leads and cardiac potential mapping on a standard spherical imaging surface enclosing the heart.
