Thick 8vo. x, 1317 pp. Figs., index. Green cloth; edges a bit spotted, else fine. Updates new information on "the field of rhythm and conduction abnormalities. This has included: very basic data on the physiology of normal and abnormal impulse formation and conduction; methods for the study of these problems in the clinical setting by such sophisticated technics as constant monitoring, ambulatory monitoring, His bundle electrography, and epicardial mapping; a better understanding of the pharmacologic mechanisms involved in the use of the standard, as well as new, drugs for the control of rhythm; and the development and refinement of pacing technics for the management of patients with abnormalities of impulse formation and conduction. The quantity of literature that has come forth as a result of these endeavors has been extensive, and the identification and assimilation of the pertinent information into the matrix provided by an earlier edition of a reference book was no small chore. Dr. Bellet has done a remarkable job in this regard. I am particularly impressed by the fact that certain areas of investigation, which have been highly active up to the time that this volume must have gone to press, have found a place in the book." – Robert J.
