The classic medical textbook tends to be overly technical, excessively detailed, profusely referenced, and the antithesis of enjoyable reading. With the expectation of many hours of hard work, I lvas unprepared for the pleasure that lay ahead. This book is what we in the United States call a « sleeper ». Without pomp or solemnity it captures you with a light-hearted style that subtly belies its sophistication. The authors have indeed mastered the art of simplicity, combining profound knowledge with an airy format, to a degree that is hard to emulate. All the salient features o. fpacing are presented here, from history and pathology to complications and long-range follow-up. Perhaps it is a mark of excellence, rather than a confession of my personal ignorance, to say that there is scarcely a section that did not provide me with a new bit of information or a new insight. Permanent pacing o. f the heart is so common nowadays, at least in the more affluent sections 0. 1' the world, that almost every person must know of someone with an implanted pacemaker. In the United States, where there are more than 100, 000 new implants each year, almost every sizeable hospital has a pacemaker implantation service and almost every physician in a related field is interested in doing this surgery. All that should really be required is that the surgeon make himself an expert.

At the end of 1976 there were 34,215 people with end-stage renal disease alive on dialysis and transplantation within the registry centers of the European Dialysis and Transplant Association (14:4, 1977). From July, 1973, when the American Government began to fund dialysis, the estimated number of dialysis patients in the United States has risen from 5,000 plus to over 35,000. Jfwe add other regions, such as Canada, Australasia and Latin America, it is safe to say that as this is written, over 100,000 people are living on dialysis. The u.s. Social Security System, Veterans Administration, Medicaid and State Agencies are now paying out over one billion dollars annually to support patients on dialysis in the U. S.A. Cobe, Redy, Travenol, Dow Cordis, Drake Willock, Gambro, Asahi, Erica and a host of other company names have become household words in many households throughout the world. I cite these factors not out of a pretense at precision or a passion for phenomenology, but simply to indicate that dialysis has become lore than this century's therapeutic miracle. (Perhaps the first treatable fatal chronic, terminal, medical disease I). It has also become big business! As such, it has perhaps become too important to be left solely in the hands of medical specialists, such as nephrologists.

The rapid progress in the field of echocardiography has created an extreme need, now more than ever, for a practical book which is concise, yet complete, well illustrated with good quality tracings and which provides the latest information on the state of the art of combined M-Mode and 2-D) echocardiography. In this book « The Essentials in Echocardiogra phy » Drs. Laurenceau and Malergue have done an excellent job of accomplishing above goals as they discuss the basics of ultrasound, normal examination, and features of various diseases of the heart. The format of presentation, the quality of illustrations and the clarity of discussion point to the thorough and broad echographic experience of these authors. By sharing their experience with us in the form of this well-conceived book, they have done the field of echocardiography a great service. A. J. TAJIK, M. D.
