Atrial fibrillation (AF) has had a rich history that has touched the careers of many of the great clinicians and investigators of the 20th century. More recently, there has been an explosion of research into various aspects of the mechanisms and therapy for AF, as evidenced by over 8,000 publications on AF from 2000 to 2007. A century of research and clinical observations, coupled with modern investigative technologies, has enabled modern investigators to have their own "fantastic voyage" as they travel beyond the cell borders into the ionic mechanisms responsible for AF and its many atrial perturbations. One can only imagine the satisfaction of Wenckebach, MacKenzie, and Lewis if they could see how their seeds of wisdom have grown into such sturdy ideas, or how delighted Scherf would be to learn that his ectopic focus theory for AF has been given new life. This paper on 100 years of AF was initially prepared for presentation as the Plenary Lecture at the AFib Summit for Heart Rhythm 2007 in Denver, Colorado. I have tried to provide the reader with some of the most important observations on AF, realizing that it would be impossible to include all or even most of the major research done during this time frame. I apologize to my many colleagues whose research has helped us to understand better the clinical and basic aspects of AF, yet who could not be cited for lack of space.
