In this edition Dr. Goldberger has retained the same general pattern as in the first edition, but with a number of changes and additions. Chapters that have been revised and expanded are those on heart failure, congenital heart disease, cardiac surgery, hypertension, and myocardial infarction. A new chapter on ballistocardiography has been added. Dr. Goldberger, who is probably best known for his work on unipolar electrocardiography, has resisted the temptation to overemphasize that phase of cardiology and has written a well-balanced, up-to-date, standard book on heart disease as a whole. It is well illustrated. At the end of each chapter there is a well-selected bibliography. This volume is recommended as a textbook for medical students and interns and as a reference book for the general practitioner.
