Experimental Studies on Auricular Flutter

The action of cardiac glycosides on experimental auricular flutter.

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...

Clinical studies on the nature of the auricular flutter.

(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...

The 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 ...

A - V Conduction in Auricular Flutter

Flutter of the auricles may be associated with either a regular or an irregular ventricular rate. The former occurs as a rule in the untreated patient, the latter as a result of digitalis therapy. An attempt was made to explain the irregular ventricular response in auricular flutter as a result of a conduction disturbance similar to that seen in sinus rhythm with second degree A-V block charact...
