Diseases of the Heart (1910)

(460 PAGES)THE speedy exhaustion of the first edition of this book, and the demand for its translation into a number of languages, is an evidence of the interest taken in the more recent methods of studying diseases of the heart. It is extremely gratifying to find many investigators entering a field full of promise of new and original observations, embracing every aspect of the circulatory system. I wish to point out that, in setting forth my own experiences, I desire to keep the record of facts apart from their interpretation. For this reason the numerous figures in the text represent the actual facts as recorded by the movements of the heart and blood-vessels, and are therefore far more trustworthy than a verbal description. The interpretation of these tracings represents the present state of my knowledge. These interpretations may ultimately be proved to be incorrect, but the recorded movements will continue to serve for other and more fitting explanations.
