The objectives of this book, as stated by the author, are to teach the "uninitiated" student or physician the basic principles of electrocardiography and vectorcardiography and to show how these disciplines may be applied usefully. These objectives are admirably fulfilled.
The standard concepts of electrical potential development and the motions of the forces producing vectors are clearly explained and illustrated. The relation of transmembrane potential fluctuations in the genesis of the electrocardiogram would have been an interesting addition to the section on "Fundamentals." The use of the cube lead system for vectorcardiography, rather than a corrected lead system such as the "Frank," is described by the author (page 62), but its acceptance may be questioned.
The concomitant presentation of illustrative scalar ECGs and vectorcardiograms is especially valuable in familiarizing the student with the significant forms of the latter. Numerous diagrams are clearly designed to illuminate the basic principles covered. Succinct
