This book was apparently designed as an introduction to electrocardiography. The sections on sinus tachycardia, pericarditis, acute cor pulmonale, the normal P wave, auricular infarction, exercise tolerance tests, and premature contractions are particularly well done. Historical background is well covered, but this seems to be at the expense of more recent work to which there are relatively few references. The format of the book, as well as appearance and reproduction of the figures, is generally satisfactory.

Certain passages, however, might be considered inaccurate. On page 64 the author refers to intrinsic and extrinsic deflections when he apparently means "intrinsicoid" and "extrinsicoid." He uses the term "compensatory pause" as referring to the pause following any premature beat. The author's statement concerning relative frequency of auricular and ventricular premature beats does not conform with data compiled from large surveys, nor are the limits of the normal P-R interval generally accepted as 0.08
