Experimental and laboratory reports : Comparison of three different systems of vectorcardiography

Abstract

The lead systems of Frank (F), Schmitt (S), and one of our own (B) are compared and the agreement is expressed by a score. On the whole, the agreement is satisfactory, but the anterior-posterior component of the heart vector is uncertain and spoils the correspondance, especially in comparing the F and B systems. A linear transformation is deduced to describe the average relation between the S and B systems.
