This is a comprehensive book on the heart from a qualified physician who is a past-president of the American Heart Association. It is a part of the Laymen's Handbook Series developed by the publisher and is an extremely well written book. Indeed, if there could be any adverse criticism it would be that, for the layman, the book is too comprehensive and contains more information than he can digest and much more than he needs. It is definitely a book which can be recommended to intelligent, well-balanced patients who are capable of objective thought. It is not recommended to neurotic or introspective persons or those prone to build up symptom complexes into major disabilities.
