This monograph is one of a series which, according to the publisher, is intended to present the practical results of research in special fields of medicine. Spatial vectorcardiography undoubtedly qualifies as such a field, but, if "practical" implies clinicaly useful results, the intention of the publisher is not realized. Wide use of the vectorcardiogram should await proof that it exceeds the range of usefulness of the electrocardiogram, and as yet such proof is inadequate.
For example, the difficult problem of recognizing posterior infarction, in which it is hoped the vectorcardiogram will be of assistance, is dismissed by these authors with the statement that such lesions may be recognized by "increased anterior displacement of the QRS sE-Loop." Without pathological confirmation, which is not furnished, such a statement is both meaningless and misleading.
The book consists of 12 chapters, the first 4 of which contain theoretical and technical discussions of vectorcardiography, while
