This work consists of two volumes, a text and an atlas. The atlas contains two hundred excellent plates of electrocardiographic tracings illustrating the cases and discussions in the text.
The text is divided into two parts. Part I contains a general discussion of the physiology of heart muscle and a brief consideration of the principles of electrocardiography, leading up to a consideration of the partial electrocardiogram. The author considers the conventional electrocardiogram a superimposition of two distinct curves, a dextrogram and a levogram. By the aid of an indifferent electrode and small chest electrodes placed in the region of the lower part of the sternum and the left axilla, curves with constant characteristics are obtained in normal man and experimental animals. These tracings the author terms partial electrocardiograms and puts forth experimental and theoretical evidence to prove that they are dextrograms and levograms. Part II is concerned with the pathologic
