This book deals first with the nomenclature and classification of heart disease and is supplemented by a section containing discussions of criteria for diagnosis, including the role of electrocardiograms and roentgenology. The book includes also an outline for the pathologic diagnosis of cardiovascular diseases and anomalies. The section on nomenclature follows in general that employed by the Standard Classified Nomenclature of Disease. The discussions on interpretation of roentgenograms of the heart and electrocardiograms are simple and constitute an invaluable guide to all clinicians dealing with heart disease. The book is well printed and the illustrations are clear. It should be in the hands of every cardiologist and internist and would prove useful to many others whose work with heart diseases is less specialized.
