The title, Clinical Vectorcardiography, indicates that vectorcardiography has become part and parcel of clinical cardiology and something the cardiologist should know about. The text is concise, clearly written, and perfectly adequate to introduce the subject. Chapters are subdivided into introducing vector concept, vectorcardiographic lead systems, the excitation wave, and origin of complexes. Each chapter is richly supplied with diagrams and, in good part, reflect the fine contributions previously published over the last 15 years by Dr. Helm. In the chapter on "Vectorcardiographic Display," the authors particularly reiterate and justify their opinion that the sagittal plane of the vectorcardiogram should be viewed from the right side in conformity with Einthoven's convention. The committee on electrocardiography and vectorcardiography of the American Heart Association consistently has advocated the left sagittal plane, an unnecessary recommendation deviating from Einthoven's convention. Therefore, all illustrations in this book are supplied with sagittal views of the vectorcardiogram from
