Excerpt from Diseases of the Heart and Aorta IN the preparation of this book it has been the writer's aim to present side by side the phenomena observed at the bedside and the facts learned in the laboratory in order to show how each supplements the other in teaching us how to observe the patient and to direct the treatment. Many of the results obtained in the laboratory have not yet attained practical importance because they have been scattered through the literature and have not reached the eye of the clinician; but wherever the clinicians have looked to the laboratory or laboratory workers have looked to the clinic for verification or application of their theories the great pillars of progress have been raised. In accordance with this idea the clinical presentation in each chapter is preceded by an introductory section dealing with the experimental pathology and more fundamental principles of the subject, which has been used as a basis for frequent reference in the clinical dis eussions. The trend of clinical observation during the past two decades has been toward more accurate study of disturbances of function and toward the introduction of mechanical methods for their observation, methods of precision which tend to supplement or supplant the older and simpler methods of physical diagnosis. Chief among these may be mentioned the study of blood-pressure, the graphic studies upon alterations in cardiac rhythm by means of the venous pulse, the outlining of the heart and vessels by means of the X-ray, and the phonographic recording of the heart sounds. Each of these subjects has been reviewed with special reference to the general principles upon which the method is based, in order to point out its applicability, its limitations, the character of information which it has yielded in clinical conditions, the conditions under which the same informa tion may be gained by simpler methods, the conditions under which its employment is essential and those under which it is superfluous.
