In 1887 McWilliam1 produced a flutter in the auricles of the mammalian heart by means of faradic stimulation of the auricles. In 1908 Hertz and Goodhart2 reported a human case in which the auricles were beating rapidly at a rate of about 230 per minute, but the ventricles were beating about 80. In 1911, Jolly and Ritchie3 applied the term of auricular flutter to those cases of rapid regular auricular contractions ranging from 250 to 350 per minute associated with partial or complete heart block, so that the ventricular rate was much slower.
Reports of similar cases have appeared in the medical literature since that time. Summaries of these cases with the addition of new ones have been made by Lewis4 in 1912, and more recently by Ritchie5 in 1914. At present this cardiac condition is well recognized as a clinical entity, and
