They stress the "vector method of interpretation," using the conventional electrocardiographic electrode positions, and believe this method should supplement rather than supplant other methods of interpretation. The authors' method, essentially, is to construct frontal plane QRS and T vectors from the routine extremity leads, and to locate these vectors in space by the use of the conventional precordial leads. The resultant is termed the mean spatial QRS and T vector respectively. They then discuss the clinical application of
