This well-written monograph records the extensive investigations on the nature of auricular arrhythmias of a well-coordinated research team whose work began in 1947. How much toil and effort must have been required is indicated in the dedication of the book: "To our neglected families without whose devotion this work would have been impossible."
For well over 30 years, English and American clinicians, teachers, and research workers have generally accepted Sir Thomas Lewis' interpretation of auricular flutter and fibrillation as being caused by circus movement. The Viennese school, however, never accepted the circus movement hypothesis. With newer, improved techniques, which include the use of a high-speed cinematograph, a dual beam cathode ray oscillograph, and a multichannel electrocardiograph, these investigators set out to reinvestigate the nature of auricular arrhythmias in the experimental animal and man. The data they derived, presented in detail in this book, led them to conclude that all auricular
