This 330-page book, the second edition, differs from its predecessor by the introduction of the concept of spatial vectorcardiographic orientation. This is accomplished not by adding a separate section on this young subject but rather by presenting a vector analysis of each topic as a basis for the electrocardiographic alterations noted. This extension of each electrical analysis is brief and is accompanied by instructive diagrams and sample tracings. The result is a discussion of each chapter, which is simple and clear, and the author thereby reaffirms himself as an able teacher of his subject. This approach also helps to remove a portion of the empiric character of traditional instruction in electrocardiography.
Division of the text into a section on basic principles followed by a section on clinical considerations provides a logical presentation of each topic from its two viewpoints, theory and application. The final section is devoted to the arrhythmias.
