چکیده
(Received for publication, February 13, 1956) It is widely known, that there are two different theories concerning the nature of the auricular flutter ; namely the ectopic theory and cirucus movement theory. In the previous papers' ),Q ) we attempted to clarify this problem experimentally and reported that the electrically induced auricular flutter is differed from the aconitine-induced flutter in their nature. The analysis of the intrinsic deflections in the direct auricular unipolar leads exhibited to us that in the former the excitation wave pro pagates in a circus way, while in the latter it starts at the aconitine-in jected portion and propagates radially. Accordingly it was considered that there are two different mechanisms in the experimental flutter which shows the identical figure . Now it must be examined which of these states corresponds to the clinical flutter. In the literature, the circus movement theory of the auricular flutter was claimed at first by Lewis3) in 1921 on the basis of the fact that the electrical axis of the F wave rotates in 360 degrees. Later, Decherd and others4) and Grishman and others5) also observed the same findings. In recent years, Wenger and otherss) and Sodi Pallares and others6) analyzing the esophageal, intracavity or precordial leads, ob tained the results explanable by the circus theory and claimed the existence of the flutter due to this mechanism. On the other hand, Prinzmetal and others8)9) advocated the ectopic theory on the basis of the nearly synchronous contraction of both auricles in the high speed motion picture recorded during commissurotomy.

Auricular Flutter
Auricular flutter was first described by McWilliam in 1887 (Mackenzie, 1925) as a result of experimental stimulation. Ritchie (1905) obtained graphic records from the jugular vein, and Jolly and Ritchie (1908) (Mackenzie, loc. cit.) took electrocardiographic tracings from one of Ritchie's cases of auricular flutter. Mackenzie looking back through his old records found cases of auricular flutter...
متن کاملThe effect of procaine amide (pronestyl) in clinical auricular fibrillation and flutter.
Procaine amide (Pronestyl) was administered to patients with auricular fibrillation and flutter in an attempt to restore sinus rhythm. Thirteen of 20 patients with auricular fibrillation had sinus rhythm re-established. Several of the patients who were not converted with procaine amide were later restored to sinus rhythm with quinidine. OR MANY YEARS the restoration of sinus rhythm in patients ...
متن کاملThe Mechanism of Auricular Flutter and Auricular Fibrillation
A DISCUSSION of the mechaniism of auricular flutter or fibrillation requires first a precise definition of what is meant by those terms. They were coined originally to designate more or less characteristic clinical syndromes, but they are now applied loosely to a heterogeneous group of experimental results that may bear only a superficial resemblance to those syndromes. Thus, it is possible to ...
متن کاملProcaine amide therapy in auricular flutter with 1:1 A-V conduction.
Procaine amide hydrochloride was first introduced clinically by Mark et al. (1950). They drew attention to its effectiveness in the control of ventricular arrhythmias, especially paroxysmal ventricular tachycardia. This has since been amply confirmed. It is the drug of choice in the treatment of paroxysmal ventricular tachycardia, taking precedence over the more toxic and unpredictable quinidin...
