This textbook on electrocardiography is written with considerable knowledge of the entire subject, and the authors are familiar with the American literature and frequently refer to it. The book is divided into four parts, covering (1) the theoretical basis and technic, (2) the normal electrocardiogram, (3) the pathologic electrocardiogram and (4) the clinical application of electrocardiography. The classification of abnormal electrocardiograms is unorthodox and therefore confusing to beginners in this country, whowill follow the American tradition. The diagnostic importance of chest leads is stressed. However, a polarity is used the reverse of that now universally accepted in English speaking countries following the recommendation of the official heart associations of Great Britain and America. It is to be hoped that the French Société de Cardiologie will also adopt the newer method of recording chest leads, so that the nomenclature will become uniform.
Most of the illustrations are well reproduced. It is
