The authors of this book are justifiably recognized for their development and popularization of equipment for the combined audiovisual study of cardiac auscultation. No one familiar with this equipment can fail to appreciate the impact of simultaneously seeing what one hears through the stethoscope. This book is the outgrowth of their experience in teaching clinical auscultation by this method.

The book contains much of the standard information expected from any discussion of the subject. However, the departures are praiseworthy.

Most textbooks in physical diagnosis outline the physical principles of sound either so superficially or so complexely that the average student soon loses interest in incorporating this basic information into his everyday and life-long analysis of cardiac auscultation. The discussion in this book is concise, clear, and meaningful. The classfication of murmurs simply as pathologic and nonpathologic is especially commendable. The majority of the more than fifty illustrations are faithfully reproduced
