This paper-bound volume presents an excellent discussion of the cardiac arrhythmias. It devotes several pages to the anatomy of the heart and then proceeds with a description of the methods of registering graphically the cardiac irregularities. One criticism might be interpolated: Much more space is devoted to the study of the cardiac rhythm by means of polygraphs and polygraphic tracings than in this country. That seems like a waste of time. The latter half of the book deals with the various types of arrhythmias from the point of view of the accompanying physiologic disorders, the clinical expression of the mechanistic disturbances and their polygraphic and electrocardiographic expressions.
The make-up and format of the book are excellent; the paper is of a high grade glossy quality on which the numerous figures are excellently reproduced. The book may be highly recommended to physicians who can read Spanish.
