This monograph is a compilation of the experimental observations on various auricular arrhythmias. The observations include high-speed motion pictures, which are correlated with electrocardiographic as well as oscillographic records. The data are presented clearly, and the numerous figures are printed well. In many instances diagrams are superimposed on the photographs, which adds to the clarity of the presentation. Without such labeling many of the photographs would be meaningless to the reader.
The authors make a convincing presentation for their concept of the unitary nature of the auricular arrhythmias. With the application of aconitine and continued electrical stimulation, the relationship of auricular premature contractions, auricular paroxysmal tachycardia, auricular flutter, and auricular fibrillation seems to be one of degree or rate. During the arryhmias occurring under the circumstances of these studies, a circus movement is apparently not present. This does not exclude the existence of circus movement flutter under other circumstances.
