PREFACE TO THE FIRST EDITION

That marvelous organ which, moment by moment and year by year, keeps consistently sending the blood on its path through the arteriovenous system is naturally one whose structure and function need to be carefully studied if one is to guard it when threatened by disease. This series of articles deals with heart therapy, not discussing the heart structurally and anatomically, but taking up in detail the various forms of the disturbances which may affect the heart. The cordial reception given by the readers of The Journal to this series of articles has warranted its issue in book form so that it may be slipped into the pocket for review at appropriate times, or kept on the desk for convenient reference.
