To introduce the student to vectorcardiography, a very brief description of the principles of electrocardiography and vectorcardiography is followed by an atlas of instantaneous vectors at 2.5 millisecond intervals, one to a page, of two normal and six abnormal vectorcardiograms. Each instantaneous vector is so located on the page that it is superimposed on the succeeding vector on the next page. By rapidly flipping the pages, the illusion of a moving vector is created.
The introductory material is less comprehensive than that found in standard textbooks of cardiology. The generation of the vector loops is thoroughly illustrated by the instantaneous
