Diagnostic Electrocardiography by Michael C. Ritota is written for the purpose of "simply, briefly and accurately presenting basic knowledge essential to the interpretation of commonly seen electrocardiograms." It is presumably designed for medical students, nurses, house officers, and practitioners who require a practical introduction into the field. It could be improved by a more current explanation of the origin, direction, and transmission of electrical forces involved in the genesis of the ECG. For example, it seems that vector concepts, the atrial and multiple atrioventricular (AV) conduction pathways, and the transmembrane potential variations of the myocardial fiber should have been introduced even to the novice. The discussion of axis variants should not be limited to the frontal plane.
The book is relatively short with 17 chapters; three are on technical phases, and others discuss ECGs of clinical abnormalities or rhythm disturbances. The format is excellent, allowing a satisfactory division of space
