Many textbooks on electrocardiography are so voluminous that the reader becomes confused at the mere prospect of delving beneath the frontispiece. The author has achieved completeness, relative brevity and simplicity of presentation in this delightful new volume. The smooth, flowing style makes for easy reading. The illustrations are frequent and of good quality. The chapter on interpretation of precordial leads is well illustrated and complete. The source references for material not original are clearly indicated. The book is well indexed. The only criticism offered by the reviewer is that where possible it would seem desirable to adhere completely to the nomenclature set forth by the Criteria Committee of the New York Heart Association rather than to substitute other, though synonomous, terms. This book should prove of especial value to students of electrocardiography.
