"The Electrocardiogram" is a concise well-balanced text covering all of the major aspects of electrocardiography. It is written in a clear and lucid style and is presented in an attractive format. This textbook should be of value primarily to the student or to the physician who is interested in obtaining a good fundamental understanding of the problems in electrocardiography. It is a practical book but cannot be considered as a reference for the advanced electrocardiographer. The book is well illustrated, and the quality of reproduction is very good. The book can be recommended as a basic text.
